I fired up my new DIY solar system which uses the Growatt 12kW Inverter + Five EG4 48V batteries + 16 440W panels (7kW maximum). Yesterday the solar power draw appeared to be being capped (full sun day). Thanks to my previous post here, I checked the inverter's Max Charge Current and I saw...

New to solar and just fired up my new DIY solar system that consists of a Growatt 12,000W inverter, 16 440W panels arranged in two arrays PV1 and PV2 going to the inverter (each array is 2 parallel sets of 4 panels in series). Also using 5 EG4 batteries. This morning the system started...

I'm building a ground mount frame that consists of eight 15' of Superstrut (10'+5') acting as "rafters" to hold 16 large 440W panels (mounted as 4 panels by 4 panels - horizontally). See attached drawing I made. The high end of the mount frame will be anchored to a solid deck. 15' Superstruts...

Is it ok for positive and negative cables from battery bank to inverter to be different lengths? Normally, with A/C, I try to keep them the same length. From my battery bank, I have negative that will go straight to the inverter. The positive will loop down to a surface mounted class T fuse...

Building new solar setup... Have four EG4 LifePower4 48V 100AH batteries connected in parallel in a rack. I also have a Growatt 12kW 48V off-grid inverter. I've completed the A/C connections on inverter. So now it's time to connect the battery array to the inverter. A few quick questions...

I'm working on my new solar build using a Growatt 12kW split-phase inverter from Sig. Solar. Trying to make sure I'm doing the grounding correctly to avoid ground loops. Please see attached image of what I have. Essentially, it's two home service panels (independent panels since each gets...
