    Tommatech 7.2kw inverter has output voltage from PV solar ports

    Pv cable connector was cut by someone and he reattached it with some tape. When it's rainy the cable would be shorted to the steel frame. And i found the copper inside cable to be all black carbonized

    The best lithium battery

    I was thinking of getting something like seplos bms so i can benefit from communication between bms and inverter, but i found out that there is several versions with different communication protocol for different inverters, which make this feature useless if one day for some reason i changed the...

    The best lithium battery

    @Hedges @upnorthandpersonal @Will Prowse @Supervstech @Steve_S sorry guys to bother you but your thoughts on the matter is appreciated. I have already ordered a custom made packs from AMY but i think it can be better with a little more money but would be worth it the extra money.

    The best lithium battery

    Definitely ! what i mean is what are the best cells (Like matched and batched cells, by the way do you have any numbers for matching like what should be the tolerance between cells ), BMS for the selected cells (brand and model recommendation), Communication port with inverter and of course...

    Data extraction from inverters

    I am very interested in this topic even though i never worked on Raspberry. But if there any document where it teaches you how to doe these stuff for a newbie it would be awesome to have all these data available.

    Tommatech 7.2kw inverter has output voltage from PV solar ports

    I noticed that my 20 kwh lifepo4 batteries are being drained with no apparent load. And almost 7000w are pulled from grid. I disconnected the solar panels, everything went back to normal. I measured the voltage on the inverter on the PV panel ports i measured 33V. I connected at 10w resistor and...

    Isc is it critical to consider in all in one off grid system? Fry or Bye bye

    I have been searching but couldn't find a clear statement about it. i noticed that All in one inverters with higher voltage MPPT 500V have lower Max PV input current approx 18A. However Isc of solar panels rated as 450W and more are usually around 10A. thus paralleling in this case will lead to...

    High voltage ( 500v) vs low Voltage (120V) MPPT

    yes this is exactly what i mean. Some MPPT controllers have PV input voltage that should be around 500V and some shouldn't exceed 120V. What other benefits -other than having long distance array- does it have, in terms of efficiency ?

    Alibaba or Aliexpress or any other sources for LIFEPO4 batteries buying experience

    The plan is clear for me: first ill be buying a hybrid 3kva inverter which should be able to charge my batteries with at least 80A. 9 Panels 400W. and the most important factor is batteries. This why I am looking for long lasting reliable batteries. In my country "Battery storage" means lead...

    Alibaba or Aliexpress or any other sources for LIFEPO4 batteries buying experience

    This is the first I see someone taking the Matching process this way, but seems more logical, all I thought that matching cells is having cells at the same voltage in order to have more balanced cells. but now the idea is much clearer thanks. Below offers were provided based on 10 KWH storage...

    Alibaba or Aliexpress or any other sources for LIFEPO4 batteries buying experience

    Thanks for the reply. i could find several threads here talking about this subject. My intention is to create a thread that will become a reference to anyone who needs to buy good Lithium batteries with the best price in any place in the world not only USA and Europe. So a Brief feedback on any...

    Alibaba or Aliexpress or any other sources for LIFEPO4 batteries buying experience

    hello, i was looking for reliable & quality LIFEPO4 and found that china has nearly 80% of the production of these batteries. So finding good sources in China won't be an issue. I only know Alibaba as wholesale trading platform for chinese products. on Alibaba there is so many companies that...
