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
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...
@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.
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...
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.
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...
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...
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 ?
