We have a large RV. It came with:
2x190w (GP-PV-190M) Go Power panels
30amp controller (GP-RVC-MPPT-30)
1,800W 12v inverter (PD1618)
We plan to boondock for several days at a time on private land (no power available).
We've purchased 2x304ah lithium batteries (4x304ah eve cells with a 100amp Jiabaida BMS) - 2 sets of these, giving us 608ah at 12v.
We also purchased 4x200w solar panels RS-M200D. I meant to order the 12v panels but was too late to cancel the order, so I've kept them.
The solar controller is outputting approximately 25amps (full midday sun) at 14v (350w), using the 4 Rich Solar Panels in series or parallel. I don't have the remote for the solar controller, and to cut a long story short, I cannot purchase one from the manufacturer as they were just bought out by another company and have minimum limits on spending, so refused to sell to me. I've tried everywhere to get one, as I think I could change settings to help improve performance?
So, I plan to replace this controller with another one. Perhaps Victron (if budget allows), or perhaps 2 smaller victron's if cheaper? One for the Rich Solar panels and the other for the go power panels.
I'm confused as to why my output didn't hit 30amps? If I purchase the Victron's, will this work, recharging at a faster rate (more amps output to the batteries)? And will I get closer to the possible output of almost 1200w?
Is 1200w too much for 12v? 100amps - my BMS can handle that, so I'm assuming that is ok (at a maximum).
I'm trying to figure out the best way forward without spending too much more on this project.
I've been told several times to go with 24v or 48v, but then I have to spend hundreds more on another inverter. I'd rather not do that. Also, I was never quite sure how I would get everything back down to 12v to supply all my 12v equipment in the RV.
Any help/thoughts are much appreciated.
