    Round heatsink block looks like it has all the high current inductors integrated into it, separate to allow for convection cooling. round shape says they potted them all in there, probably in a flexible thermal compound. Those mosfets likely are some special order, a regular one with an overmoulded, or a stick on plastic top, that they use to have good thermal transfer, but also allow easy mounting with a single screw through both board and mosfet. Either done by them, or they got some fab to make the new moulds to use standard off the shelf devices into a special package.

    Very common to have fan inside of high ip class devicess to prevent hot spots and therma difference in power components, sometimes there is two heatsinks back to back to improve internal air cooling. My experience is that dirty dust kills those high power boards, not heat.

      I discovered that with a battery charger, it's a completely sealed unit and all of a sudden I could hear a sound coming from it. There was a fan inside even though it was sealed. I guess it would help move air inside internally and equalize the temp more, and it would slowly dissipate through the case.

    I've had one of these inverters (at least the South African version of this 5kW unit) for the past year and it's great. Solid quality and fantastic bang for buck. A tiny bit slow to switch if grid goes down (perhaps a few ms more than ATX spec), which happens a lot here, so I've found one or two sensitive appliances just just doesn't have enough capacitance to cope. I've just added a normal UPS in front of them.
    Also running completely passively, so fan may just be if you're running at peak power for extended periods.

      What's the maximum amperage rating of the panels you are using? I am reading a lot of contradictory information on that maximum amperage of the panels. The inverter says 13A per mptt. Others are saying the maximum amperage of the panels needs to be 13a while others are saying the panel amperage is not important as long as you take care of the maximum Voc.

    Very cool. For those that don't know, some people primarily want backup power in case the grid goes down, but that isn't hooked up to the grid, so it will likely just sit there 99% of the time. So its very expensive for little use for most people. Some people want a lower electric bill, so they feed power to the grid (after they make a deal with the power company), but the grid might not pay enough for extra electricity to cover the initial cost and maintainance of the system. Plus everything shuts down when the grid goes down, so you are without power even if it is sunny when you just have a grid tied system when the grid goes down. Hybrid inverters are the simplest solution to let people contribute to the grid, and then to disconnect from the grid in order to use the solar panels and batteries to power the house when the grid goes down. It all boils down to how much you are trying to save money for electricity versus how much power you want available when the grid goes down.

    • @NiHaoMike64

    I Love Deye Inverter (I have the 3 phase sun-8k-sg04lp3-eu myself )
    The three phase one can be disassembled more easily.
    The inverter also comes with current sensing coils for Grid side
    so you dont even need a smart meter when the inverter is near the grid feed!
    They are one of the most advanced out there and the support from Deye is also not bad.
    When it comes to maximum Power per String it is very important not to go over the the MPPT Voltage Limit and maximum Current
    If you have under -1°Celcius in Winter you can add +1V for each Panel.

    I've had the 12kW 3-phase Deye running here for 18 months, the first winter just as a UPS system for my whole house.
    It runs absolutely smoothly and the switchover to battery operation in the event of a power failure is so fast (7ms measured) that nobody notices.
    The GEN connection can easily take the rated power from microinverters and feed it through the device to the grid, which means that the energy from the microinverter can also be charged into the battery, which is useful in bad weather when the connected PV modules produce less power.
    In addition to the Victron devices, the Deye can also modulate the grid frequency of its island during a blackout to throttle connected dumb grid-tied inverters.
    It's a real shame to have bought such a 5 kW toy. This Deye is also available in single phase up to 16 kW and would probably work as a UPS system for your whole house.

    The transistor clamps are separate to the devices, if you had a close up it would be more obvious but they are a clamping bridge over moulded with an insulating encapsulation. The devices are standard TO-247's.
    You will find it in other inverter designs as well. Seems to be somewhat of a defacto standard of sorts for Chinese inverter designs (or maybe there's one particularly prolific designer that keeps using them?). The clamp isn't some part that appears in a catalogue though.

    I honestly worry about the future and how energy demands will be met... 5kW is massive but it's really nothing if you expect that future homes need heating/cooling and car charging all from electric. Both the batteries, the PV, and the inverters all need to get 10x cheaper and better for there to be much hope in powering future homes, I feel. My previous apartment had electric hot water (for shower etc), with gas-powered heating. We were using 10-15kWh per day in a home of 3 people. If the entire heating would be through HVAC, it'd easily be 30-40kWh per day. For that to be with energy storage, you'd be looking at a 50kWh battery lol. And that's just a moderately sized apartment...

They can "push back" / supply power onto the grid line (and the generator / aux line). They use a CT coil on the Grid input into the house (not sure if you are allowed to use them in this configuration in Australia) to measure (and thus control) the power output to ensure that you don't feed back onto the grid itself. Thanks for the great videos.

    In South Africa, the market is saturated with this product, to the extent that local government has endorsed this brand for solar installations. I own the 8kW Sunsyk version, which is essentially a rebadged model with advancements in the firmware and mobile app.
    Key observations.
    Inside the cylindrical heat sink, three sendust cores are stacked per trio, serving the high-voltage DC to DC boost stage, boosting approximately 400V. The system includes several groups of switches that facilitate multiphase conversion. A TMS320 DSP orchestrates the process, supported by an array of IGBTs (NGTB40N120FL3W) sitting in a plastic mold with boost blocking diodes. Additionally, there are two independent trackers for PV1 and PV2, each capable of handling up to 425VDC each.
    I love this product pretty stable and has a mobile app to tweak settings and observe real-time solar production ect.
    This highlights how hybrid inverters' advancements have become widely recognized, largely due to research and development efforts and manufacturing in China.

    Aslo you can connect additional AC-couples inverter or a mincroinverter system with total peak power output of 5 kW or less even if you already have 5kWp solar connected via DC. It will allow to feed 5kW to your loads and 5kW to the grid at the same time. Or you can export power from AC-couples side and use DC side to charge the batteries. And full 10kW of solar will be available off-grid.

    Deye and Sunsynk are AFAIK brands for GlobalTech China Ltd. and just tweak the recipe for their target markets. I'm in the UK with a Sunsynk 5kW - same as this one just the on/off switch is underneath instead of on the side. It's in its 3rd year of operation and performing superbly. If they can put up with sandy, hot and likely humid African conditions then they'd have to be built pretty well. I guess if you need to dismantle these for repair then it's a pretty major overhaul anyway, like replacing all the capacitors, etc. Mine is mounted indoors in an unheated space because batteries sit below it and are not waterproof. The space beneath the heatsink is perfect for 3x 90mm PC fans which keep the operating temperature very cool and I highly recommend in this situation. Very configurable via MODBUS and my only complaint is that there is no way to directly control the internal GRID relay; I like to operate off-grid in the summer with the GRID disconnected and have to use a separate external relay for that. This avoids any energy bleed into (or from) the grid but allows my separate control system to turn it back on if batteries get too low.
    I can also confirm that the left-hand side is for the DC conversion electronics which works the hardest as it deals with high currents through the batteries. The right side runs at a lower temperature and probably just does the a.c. stuff.

    Good choice, I was going to go with this for my ESS battery system, but I went with Victron instead. Partially because it's smaller/lighter, but also I prefer transformer based inverters as you don't get DC coming out of it which causes blinding of RCD's.
    Also I didn't like SunSynk's (rebadged Deye) warranty terms. You've got to get it installed by an electrician and send them pictures of the install and stuff or you have 0 warranty, where as with Victron they don't require any of that.

      Guess it would be more correct to say low frequency vs high frequency inverter. LF needs a huge toroid and HF can use smaller transformers, but the LF ones do all the mains frequency inverting at the low voltage stage, so any DC content is on the secondary whereas with HF, the switching is done on the output of the transformer, meaning DC gets into the mains.

      nastechsolar.com/content/SOLAR%20PANELS/LONGI/Datasheet%20LONGi%20Hi-MO%20X6%20565-585%20Explorer.pdf
      In the datasheet of solar panel there are two conditions STC (Test condition in lab at 1000W/m2 irradiance) Where are NOCT (Nominal Operating Cell Temperature) at 800W/m2 at 20 degree C. All the values on the backside sticker is at STC which are the Lab numbers are sometime possible in real condition when clouds are really bright and temperature is cool. Else consider NOCT + Temperature Coefficient of Pmax. Also consider the open circuit voltage at STC because when the condition is just right and batteries are full and load is very minimal or no load, panels will go to the Open circuit voltage at STC and that is the worst case on the max voltage side.

    Do a Victron inverter next! The High frequency vs low frequency topologies would be very interesting. I work in the solar industry in SA and the debates between these two brands (essentially SunSynk vs Victron) is heated! Especially wrt. Grid harmonics and the inductive storing of energy in the larger Victron transformer.
    Both nice inverters, but I do feel that SunSynk/Deye is playing catch-up with Victron wrt. software, monitoring and control.

    1:28 Your 3.33kWp per string would be fine. That'll be the panels' STC specs, rather than the NMOT specs, so you'll have a bunch of losses before you get to the inverter's MC4 connectors. Plus any age-derating on your panels. So, providing you're not planning to chill your panels on peak solar days, you should be golden. And 6.66kWp for the two strings on a 5kW rated inverter is spot on the 4:3 max DC-provisioning ratio for Australian STC compliance.

    I just got a big 19.2kwh home battery but I would not have considered this inverter - low voltage batteries. Sure you can plug any kind of battery in to it but for higher power applications I'd much prefer HV batteries. My particular battery peaks at 438 volts and the 10kw hybrid inverter can go up to 560 volts and both charging and discharging can be done at the 10kw limit from solar or grid. It's also interesting how thin the battery wires are yet they don't heat up with that much power..
    Btw the AC coupled bit means it can already use your Enphase inverters without rewriting them. If it's CT is after the Enphase and it wants to charge the battery it will pull from the grid circuit to ensure zero import/export.

I had a car insurance claim denied because our son had driven a car registered in my name and it got damaged on a parking lot in his absence.
