I know copper is much better. I made a mistake. I bought a bus bar set to connect two battery packs to my inverter, I thought someone here had bought this one before and said it worked well, but maybe they bought one that looked like it but this was the cheap brass knockoff. Anyhow, I bought it...

We have had our grid-tied 7.5kW array for a little over a year and a half. I looked at the stats randomly this morning and it has recorded 18.8 MWh produced. Granted this was installed by a contractor (I had no desire to be installing 400W panels on my 2 story roof by myself!) So my ROI isn't...

I was reviewing my (still pending) inverter install to AC couple with my Chilicon microinverters. My planned DC wiring side is below. However, I was looking at the Radian installation manual again to review and saw they want 175A breakers on each battery input. I was putting 250A class-T fuses...

Before I got the solar, I got a Champion 3500W continuous/4250W peak inverter generator to run critical stuff in case of an extended power outage. My inverter I have now (Outback Radian) uses 240V split phase input, and has a generator input that can be current limited to the size of the...

I have an old APC Smart UPS Sua1000NET that runs my modem, router box, NAS, etc. Every few years I have to replace the pair of SLA batteries in it as they get weak (they sit charged 99.9% of the time, rarely does the thing cycle). Recently it started to complain again that the batteries were...

I have 7.92 kW (by label) of grid tie using Chilicon microinverters. I'm in the process of adding AC coupled battery backup for a few reasons (want backup in case of grid failure from a storm, or grid instability due to geopolitical stupidity, or whatever). The upcoming Outback Mojave looked...

I have 32 cells I'm putting into 16s packs, each with its own BMS. My setup is going to be stationary, although if I need to move things around I want it "relatively" easy to move (not that 160 pound battery bank is ever going to be "easy"). 1) Layout. Having 16 cells in a row would be more...

I received my JBD 7S-20S 300A contactor BMS yesterday. It has dual 4AWG wires on each connection. I'm only expecting 200A at full load (fused at 250A). I may end up having to replace the black wires off the contactor if it won't reach my bus bar I'm using to join two packs together, or if the...

This is my current setup. Note that nothing is to scale (wire length etc, just a connection diagram). This is what I'm intending to do with the upcoming Outback Mojave inverter to manage the storage/changeover and allow my GTI setup to continue functioning in the event of grid failure: The...

I'm considering the following setup: 16 EVE230 cells from powerwholesale 8kW Outback Mojave inverter (whenever it becomes available) I was looking at using the JK 200A BMS for the cells, partially because I like the 2A active balancing feature it has compared to JBD. Then I started doing...

Hi everyone, I've been lurking for a few weeks trying to read up on stuff. Now I'm looking for some expert advice on what I'm thinking of accomplishing. First off, I'm located in Central Ohio. 11x Chilicon CP-720 microinverters connected to a 8.3kw array on the roof of the house facing...
