Hi All,
I have below off-grid setup at the moment for power most of my DC devices (lights,router,nas,nvr,etc..) on my remote house.
- 2x JAM solar 460W panels in parallel this
- victron smart solar mppt 100 1 20 charge controller (12/24/48v)
- 12v 100AH deep cycle Sealed lead acid battery
I'm not sure these panels are too much for the controller. and most of the time I can only see max 291w of P Max(photo_2022-03-19_18-47-39.jpg). does this means controller reach it's maximum capacity?
I'm planning to upgrade my setup to more powerful AC off-grid system to power my entire house. also to run smaller server rack.
I'm planning to buy below new items
- 4x sok 206Ah lifepo4 batteries
- or 1x jakiper 48v 100ah rack mount lifepo4 battery
- Meanwell TS-3000 inverter this
If I purchase these new equipment, can I use them with my existing PV array and charge controller ? or do I need to add more panels or change my charge controller ?
if can use, do I need to connect panels in series ? since each panel Voc is only 50.01V?
I was planning to buy 12v inverter with 1x 12v LFP battery. but on many sites I saw that if making off-grid setup more than 3000W better go with 48v system. invert from 48v->230v is better than 12v->230v as many sites suggested. Is this true ? my usage is not more than 2000w. but for future improvement I would like to have 3000w inverter.
