Without any cables on the inverter at all I used a multi-meter to test continuity at different points on the inverter. The neutral and ground for the AC side are bonded, so I do get continuity there which makes sense to me. However, on the DC side if I touch the negative DC cable connection...

I've tried to answer this myself but there are so many tables out there it's hard to know, so I was looking for some direction. I have 2x 12v 100ah batteries in parallel. Individually they can deliver 100amps, so in parallel I'm looking to size wire for 200 amps. Everything running from the...

My current setup is a 2s2p configuration with 4x100w 12v panels so 24v (48.6 Voc) running at just over 10a isc. I have no fuses with the configuration and the disconnects would be just for disconnecting, not over charge protection. I've been told by some that 2 pole disconnects are the way to...

I appreciate all the help this forum has given me thus far. I think I have an understanding of what I'd like to do. Could you please look over this wiring diagram and see if anything looks off to you? I'm using 2awg cables for a lot of the heavier load connections which I realize may depend...

Running 4x12v (24.3voc) panels in parallel keeps voltage at 24.3 Voc while if I run 2s2p I'm at 48.6Voc. I understand the efficiencies gained of running the 2s2p configuration but I'm getting those at the cost of upping the voltage of the system. Does this make it inherently less safe should...

I have the Renogy 400w solar kit. The panels have: 15a max series fuse rating Short Circuit Current (ISC) 5.21a If I run the 4 panels in parallel I'd be up to 20.84a (5.21x4). If one of the panels shorts and the other three panels decide to take the path into that panel they would only be...

I am building a camper van setup and plan to run 4x100w 12v solar panels in 2s2p. This will bring the panels up to 24v with an Voc of 48.6v. (I mention this just because I've heard that 50v DC is where you need to be more concerned about grounding). Anyway, right now I'm running every...

I ordered the Renogy 400w solar kit. It comes with a 40a MMPT that has a max PV Input Voltage of 100w. It also comes with 4x100 watt 12v panels. I'm trying to determine the wiring for the solar panels (4p, 4s, 2s2p). Depending on what numbers I use from the website I'm not sure the MMPT can...

I am building out my van/RV setup and am trying to figure out what size converter to purchase. I feel I've narrowed it down to the PM-4 or PD Lithium line as both support constant voltage lithium compatible charging, but I don't know what size amp converter to purchase. Battery wise I'll be...
