Hi Sir, Thanks for reaching out to LuxpowerTek, Could you please send us your SN to marketing@luxpowertek.com, we need to unbind your dongle first.

Thanks for your trust with LuxpowerTek

Hi Sir, Thank you for your trust and support in LuxpowerTek. Let me clarify your questions: 1. MPPT Configuration The SNA 12K inverter is equipped with 2 MPPTs and 4 strings, with each MPPT supporting 2 strings. 2. Panels Connected to a Single MPPT All PV panels connected to the same MPPT must have the same orientation, power rating, and quantity per string to ensure optimal performance. 3. Panels Connected to Multiple MPPTs You can connect arrays with different orientations, power rating and quantity to separate MPPTs without any issues.

​@@LUXPOWERTEKwhy is it necessary that panels connected to the different MPPTs must have the same number and same power? Doesn't that defeat the purpose of having multiple MPPTs?

@@adon8672 Hi Sir, Thank you for your question, and please allow me to modify my earlier response. I apologize for the mistake in my previous answer. To clarify, each MPPT operates separately, so there is no requirement for the same number or power rating of panels across different MPPTs.

​@@LUXPOWERTEKthank you for the prompt response. I also appreciate your willingness to admit your mistake and update your initial (erroneous) answer.

Hi Sir, thanks for reaching out to LuxpowerTek. If you connect SNA 6K to the grid, and if you wanna to sell power to grid, you can enable the function" Export to Grid". If you don't want to sell power, just leave it to the default mode.

@LUXPOWERTEK Thank you for your answer. I don't want to sell energy to the grid. I only want to know if in offgrid mode in winter there is no energy from the sun and I want to charge the battery from the grid, can the inverter try to affect the grid in some way, or if in offgrid mode it will try to export at least a few Watts to the grid. I am prohibited from exporting even a few Watts, will it affect the grid even minimally when charging the battery from the network? Thank you and best regards

@@manieek5600 Hi Sir, In normal mode, if you connect with grid and there is no power from PV panel, the battery will be charged by the grid. If you are prohibited to sell power to grid, please disable the function "Export to Grid". If you have any further questions, please contact me via: marketing@luxpowertek.com

Hi Sir, Yes, our SNA 6K has the separate GEN port with the multi-functions, which can connect with Generator or AC coupling or smart load.

Hi Michele, thank you for your trust and understanding! We are committed to solving any challenges and ensuring the availability of our products.

Hi Sir, thanks for your reaching out to LuxpowerTek. Could you please describe more details?

Hi Sir, thank you for reaching out to LuxpowerTek. Regarding your question, due to hardware limitations of the old SNA 5K model, it unfortunately cannot support upgrades to include the smart load feature or AC coupling through the GEN port. We apologize for any inconvenience this may cause and appreciate your understanding.

Hi Sir, Yes, SNA 5000 supports to parallel 3 individual units to be a three-phase system.

Hi Sir, Sure, this inverter, which we refer to as off-grid, is ideal for areas where on-grid regulations are strict and selling energy to the grid is not allowed. The inverter can work with the grid, PV, battery, generator, and existing grid-tied systems.

@LUXPOWERTEK If it is connected to the grid, is it possible that it will try to send something to the grid?

Hi Sir, could you please share more details to marketing@luxpowertek.com

Hi Sir, The SNA 6K’s separate GEN port supports connections to a generator, AC coupling, or a smart load. The AC coupling function allows integration with your existing grid-tied system, enabling it to serve as an AC power source through the GEN port.

Hi Sir, thanks for reaching out to LuxpowerTek. Please contact your distributor to create the installer account for you.

Hi Sir, Thanks for reaching out to LuxpowerTek. Please kindly contact their toll free number: 1800570876

Hi Sir, Thank you for placing your trust in LuxpowerTek. The SNA 5K shares the same installation process as the SNA 6K, with some differences in parameters. However, please note that the SNA 5K does not support the separate GEN port function for smart load or existing grid-tied applications.

Hi Sir, Thanks for reaching out. please refer to our TikTok channel to view the CT connection: www.tiktok.com/@luxpowertek/video/7438923313335881003

Hi Sir, Could you please share us with your SN to marketing@luxpowertek.com?

Hi Sir, thanks for your suggestion. The smart loads or existing solar system can be connected into the GEN port of SNA 6K

Hi Sir, Thank you for sharing your thoughts! It's important to note that both high-frequency and low-frequency inverters have their pros and cons, depending on the application. High-frequency inverters are designed to be lighter, more compact, and cost-effective, with better efficiency in most scenarios. Modern high-frequency designs include isolation on the DC and PV side for safety, advanced SPWM modulation to minimize grid pollution, and lower installation costs due to reduced wiring requirements. They also handle half-wave loads like heating rods more effectively compared to low-frequency inverters. On the other hand, low-frequency inverters tend to be bulkier, less efficient (generally below 90%), and have higher idle power losses due to constant iron loss, especially under light loads. Additionally, their adaptability to unstable grids can sometimes be limited. Ultimately, the best choice depends on the user’s specific needs, such as system size, efficiency requirements, budget, and compatibility. We encourage everyone to assess their unique energy storage needs and choose the most suitable technology for their application. Thank you again for engaging with us, and we’re happy to answer any further questions you may have!

Hi Sir, thank you for your suggestion. We have shared your feedback with our product department for further consideration.

Hi Sir, thanks for your trust with Luxpower, could you please share us with your contact information to marketing@luxpowertek.com?

Hi Sir, thanks for reaching out to Luxpower, which product do you use? SNA or hybrid series?

@LUXPOWERTEK SNA 5000 Hybrid Inverter

Hi Sir, thanks for your reaching out to Luxpower. Do you install some PV panels with SNA 5K? if so, yes, you can connect this SNA 5K system into the Smart Load port of SNA 12K as the AC coupling function.

Thank you for your quick response@, SNA 12K has a Generator Port and a Smart Load Port. Just to confirm, does this mean I should connect the AC output of my SNA 5K to the Smart Load Port in SNA 12K? Does this imply that I need to choose just one feature between using the Smart Load Port for AC Coupling or as a Smart Load? Next question: If I have implemented AC coupling between the SNA 12K and the SNA 5K (configured with independent PVs), and the PV production of the SNA 12K is sufficient to meet the load while also charging the battery with the surplus, will the PV production of the SNA 5K also contribute to charging the battery till the charge threshold/limit configuration is met?

One more sir, can i use AC coupling beetwen SNA12k and SNA5k while I disable the export grid Feature? I just need to utilize my old Inverter (SNA5K), to my current PV system (now using SNA 12K) Thx before

@@indrapraja3669 Hi Sir, You can connect the AC input of your SNA 5K to the Smart Load port on the SNA 12K. Regarding the Smart Load port functionality, it supports connecting either smart loads or an AC coupling system. Please note that only one device can be connected at a time. As for your third question, the PV power from the AC coupling system (SNA 5K system) will be integrated into the SNA 12K system, helping to charge the battery and power the load together.

@@indrapraja3669 If you want to use AC coupling and do not wish to export power to the grid, you can disconnect from the grid and let your system to off-grid mode. However, if you want to connect to the grid, you will need to enable the "export to grid" setting.

Hi Sir, could you please contact your device supplier to check their user center on Luxpower Web monitor? The installer code is in the user center interface.

Hi Sir, thanks for your reaching out to Luxpower. Do you have the installer account for monitoring? if so, please login into the account, and enter into the user center, you can see the installer code in your user center.

Hi Sir, Thank you for reaching out to Luxpower. Regarding your request, you can set the working mode to "AC First" and configure the start and end times between 00:00 and 23:59. This will prioritize grid power for load consumption, while the PV power will be used to charge the battery. Additionally, you can set the stop discharge threshold for the battery between 20% and 30%. Once the battery’s state of charge (SOC) reaches the set value, it will stop discharging.

As shown in the video, if you don't enable the AC coupling function, the existing on-grid system will not integrate with the hybrid system to either supply power to the load or export surplus energy to the grid. In a hybrid system, the scenario you described is a typical application: when there is surplus power, it can be exported to the grid.

Hi Sir, thanks for your reaching out. The warning of checking polarity before turning on the inverter is for all polarities.

Hi Sir, Thank you for reaching out to Luxpower! If I understand correctly, you’re looking to parallel the GEN 6K and LXP 6K, right? Please note that these two models are not identical, as they are equipped with different firmware versions. Unfortunately, this means they cannot be paralleled into a single system. Let me know if you have any further questions or need assistance!

@@LUXPOWERTEK no not parallel, since they are not same equipment; what I'm asking, is what is the best optimal setup for the two different model to work in providing power for whole house.

@@sanusijr Yes, for what I understand that you want to add one GEN 6K system to work with the existing LXP 6K system to power your home, right?

@@LUXPOWERTEK yes, what would be the best setup. I'm planning to add a new gen 6k with battery to my existing lxp-6k which currently has its own battery.

@@sanusijr Ok, I got you, did you install the PV panels in the LXP-6K system?

Hi Sir, thanks for reaching out to Luxpower, please view our website luxpowertek.com/hybrid-single-phase-inverter-gen-lb-eu-3-6k, for the datasheet and manual download

Hi Sir, thanks for reaching out to Luxpower, could you please share your contact information to marketing@luxpowertek.com, our sales will contact you soon.

Hi Sir, Thanks for reaching out to Luxpower. The reason for recommending a maximum generator capacity when connecting to our inverter is to ensure the system operates efficiently and meets basic household power needs during emergencies, such as nighttime outages when the battery is depleted. Our GEN 3-6K has a breaker at the GEN interface rated at 40A/230V. This means the generator’s output current to the system will not exceed 40A, regardless of its capacity. Connecting a generator with significantly higher capacity would not provide additional benefits to the system and may result in unnecessary waste of resources. Therefore, we recommend selecting a generator size within the specified range to optimize system efficiency while meeting the household’s essential power requirements.

Hi Sir, thank you for reaching out! All product installation videos are on our to-do list, and we look forward to sharing them with you soon.

Hi Sir, thanks for reaching out. Do you mean that you reset the router password, right? if so, please reconnect the wifi dongle again according to the manual.

Hi Sir, Thank you for your question. As we know, In Italy, the connection of inverters to the electricity grid is regulated by specific technical standards and requirements established by ARERA (Autorità di Regolazione per Energia, Reti e Ambiente) and other authorities. One of the key standards is CEI 0-21, which defines the technical requirements for grid-connected inverters to ensure safety, stability, and compatibility with the grid. ARERA enforces these regulations to guarantee compliance with the national electricity grid's operational standards. If an inverter does not comply with the CEI 0-21 certification or ARERA's regulations, it cannot legally be connected to the electricity grid. These regulations are designed to protect both the grid infrastructure and end users. If you'd like more specific details or guidance on the requirements, feel free to reach out, and we’ll be happy to assist further.

@carminecaira8118 assolutamente d'accordo con te.. mi aspettavo una guida su come configurare correttamente l'inverter lato software avendo diverse possibilità di gestione

​@@LUXPOWERTEK Is it possibile to have an e-mail contact to direct discuss some of technical topic not covered during this webinar?

@@carminecaira8118 Hi Sir, yes, please send to marketing@luxpowertek.com

Hi Sir, Thank you for your support of Luxpower. Could you please share your contact information with us at marketing@luxpowertek.com? A dedicated representative will reach out to discuss more details with you.

Hi Sir, Thank you for reaching out. Are you interested in understanding the working principle of CT in a solar system? The CT detects the inverter's input and output currents in real time to ensure proper system operation. When connected to the power grid, the CT monitors the direction and magnitude of the grid current flow, determining whether power is flowing from the inverter to the grid or from the grid to the inverter. This functionality helps prevent excess power from being fed back into the grid. Additionally, our inverters offer a one-button setting, "Export to Grid," which allows you to disable power feeding to the grid. I hope this explanation addresses your concerns regarding the export-to-grid function. If you need further information or assistance, please feel free to let us know.

@LUXPOWERTEK Thank you, but I'm asking if I enable export to Grid and set it to 0% will the inverter power my non essential loads and not export to grid? (therfore charge batteries, power essential AND non-essential). Where non-essential loads are connected on the input side of the inverter?

​@@christoffkruger If you need to power the non-essential load and not export the power to grid, please disable the function" Export to Grid". If you enable the function" Export to Grid" and set it to 0%, also can reach not to export excess power to grid. Please don't worry for the non-essential load if the utility is always on.

If I enabling Grid Always On - it works, but takes a power from a grid directly instead batteries.

​@@artemchubenko Hi Sir, thanks for reaching out. Yes, the smart load function operates based on the inverter's default mode if "Grid Always On" is disabled. You configured it by setting the Smart Load Start SOC to 100% and Smart Load End SOC to 40%. This means that when the battery SOC reaches 100%, it will begin discharging to support the smart load, and when it drops below 40%, it will stop discharging for the smart load. However, if you enable "Grid Always On," the smart load will remain active regardless of the battery SOC.

@ thanks for prompt answer. However when I turn it on, the energy is coming directly from grid instead of batteries. I just want to figure out. That should to be like that or I am missing something.

@@artemchubenko Hi Sir, have you checked the SOC of battery, if the battery SOC drops the value of on-grid cut off SOC in the battery discharging option, the battery will stop to discharge to take the loads(including the smart load).

Hi Sir, thanks for your reaching out. The model you're referring to is the SNA US 6K, which is our split-phase version designed specifically for most regions of Americas. For the Vietnam market, we offer a single-phase version known as the SNA 3-6K. These models are tailored to meet the specific requirements of different regions.

@LUXPOWERTEK thanks 👍👍👍❤❤❤
