What could be the problem

I have installed a 5kva inverter OPTI but the solar panel icon is not showing up on the display

Bettery gel 200 ah 12 v How much price

Hello! Can you plz advise that is this can be used with APC UPS instead of solar inverter

what phase 2? AC only got single phase & 3 phase. LOL

Can it be wired in parallel to add units

Hello, please is it compulsory to use dc breaker between battery and inverter? If I use normal AC MCB will they be any issue?

Very nice

So nice of you brother ❤🎉

Hi leo so if i have 3 of these lithium batteries on the address of the third battery i need to lift the third line

Nice.

Hi Can you tell me the name of the software?which software you have used

I have such an inverter only the more powerful 5kw. 48v. I do not have a batery. The inverter display fluctuates between 30w and 50w, the panels give about 260v. So in my case, it looks like the inverter has some defect. It does not work if I connect a load it turns off will you help solve this problem error code 015.

Price ?

i need manual please send me email for model EP 3.5kw HF inverter

What is the point of making the video if you are not showing us the screen of the inverter???

Bonjour, quel est la marque du BMS et le type.? Merci à vous

Nice

Very nice video!

Leo, Good Video.... I agree with your explanation regarding parallel battery example "A", defiantly not the way to go. That first battery will be hit the hardest and will probably be the first to reach the EOL. I disagree with you on battery examples "B" and "C". Example "B" would be the choice for the best functioning parallel battery system. In this design you are forcing all batteries to consistently draw the same amount from each battery as the output terminations are on the first and fifth batteries, so each battery needs to perform. This is the same design that the "Flooded Battery" manufactures suggest to individuals that purchase multiple batteries use. The key point is that the 2 cables that connect the batteries to the LOAD are of equal length. The problem with example "C" is that even though they are all tied together at a common point the internal characteristics (SOC, internal resistance, BMS...) of each battery will not be equal across the batteries thereby causing some batteries to carry more of the load. If you want you can send me 5 of your Bonjour solar batteries and I will be more than happy to run them through different connection testing and isolating the performance of each battery through their "Charging" and "Discharging" cycles. It would make for an excellent TH-cam video(s) that I would do. Have a GREAT day!

can we monitor battery data through wifi online?

Thank you. This was very informative.

Thanks!

What app are using on the phone

How much is it?

I perched this inverter in UAE

How do you connect this parallel system to the inverter? Can you connect to inverter without comms

Thanks a lot.

Good job

How much is the price for 120kwh storage system?

Great job

Do they make Mppt solar charge controller seperately?? If yes then what is the cost in dollars??

Good job. Please, can I have your WhatsApp contact?

Great 👍 we need more video

Hello Eric. Do you know if your bateries comunicate with huawei inverters?

In 24v how many solar panel will you put all and how many watts per panel...Minimum

Is the rj45 ports the same ? Thought one was COMM while the other CAN? and how is it connected in a case of maybe 5 batteries?

This helped, what is the addition if you have 3 pieces of those batteries

Hello, Can I use LIFPO4 battery for this inventer ?

do you sell Bonjour brand in South East Asia as well??

Hello. Your bateries can comunicate with any inverter. Fantastic! Great job

Very good video. This way we can see that your bateries can communicate with any inverter.

Bonjour Leo Quelle app pour android pour connecter le telephone? Est il imperatif de brancher le cable de communications? Merci

Thank you Leo, great videos. Quick question for parrallel batteries, you did put address 1 and 2 . will this work if you pick address 0 (non of dip switch up) and 1 (first switch is up)

How much watts pv can 12kw take

Ni hao Explane system v good

hello，leo！请问您的公司在哪里？主要能覆盖那几个国家的市场啊？

Very useful information thank you❤❤❤

We are use same solar panel, on grid and off-grid same time.
