Preview thumbnail for GROWATT 3500W 48V ALL-IN-ONE . In the manual it states with lithium batteries you connect a RJ45 from the all-in-one to the BMS on the battery. Is the RJ45 cable needed? image

Preview thumbnail for Off-grid all-in-one: The Mpp LV6548 user manual states that the load of each PV input can't exceed 18amps but in the recommended section (highlighted in red) it says 6 panels in Series and 2 strings. the recommended panels are 9.79amp... so wouldn't those 2 string exceed the 18amps? image

Preview thumbnail for offdgrid: this Mpp LV6548 has essentially 2 mppt controllers in the all-in-one. Each side can accept 4000w (250VOC)for a total of 8000w .I have 10- 455w panels. My question is could one mppt do 6 panels (3s2p) and the mppt side do 4 panels (2p2s)? The reason im asking is because of some shading. image

Preview thumbnail for I'm looking at see all-in-one solar controller/inverter/ charger. I see some say 60-150vdc and some say 120-500vdc. Is this referring to the panels is series? image

Preview thumbnail for Going to buy a 4 string combiner box. My question is can each string consist of different panels. Example: first string has 4 -200w panels in series(total 800w) and the 2nd string has 2-300w panels is series ( total 600w) image

I have a off-grid cabin with a 48v solar system. I have four 12-volt 100 amp hour batteries connected in series to make a 48 volt battery. it's going to an all-in-one. Could you introduce one individual 48V 100 amp hour battery to my system. ?
