I went with two 200 watt solar panels from Rich. Fit perfectly and seems to be working well. No complaints on quality of build.

Hmmmm...didn't know that two bms with batts would allow the total amps of 100A.

I really don't know if the number of batteries matters. If there are two BMS's, one for each battery, I don't know if that means one can use a 100amp charge or if one is still limited to 50A. I don't think one of the batts would go offline UNLESS the 60A charge triggers one or both batts 50A...

Hmmm...80amps may be an overcurrent...although I am unclear how two BMS's (each limited to 50A) in parallel will read respond. I am now leaning to the 2 stage 60a unit.

I have two SOK 200Amp 12v Lithium batteries on order. I will connect them to my RV roof solar panels and replace my current RV (12v) converter/charger to a PD-4100L (12v) to provide DC to the van and also charge the lithium batts. I have a choice of 45, 60, or 80 amps charging. The two batts...

I know you didn't address this to me, BUT... I'm not concerned with getting the state of charge as I have two separate monitors, the solar controller AND a Bogart monitor for the entire system (including the energy from the RV converter-charger). As they are (or will be) lithium compatible my...

I'm was a tad confused BUT I think I know why. Isn't the above a typo, it should be 3000/.85/24 volts? So I have a high freq. inverter of 2000 ac watts/.85/12v (which is my system) = 196a A 'de-rating' at .8 adjusts to 245a. Now I intended on having two 4S 12v batteries of 200A each, the...

Well... I guess that would make do till Overkill is restocked.

I don't mind a larger size, but I was basically trying to emulate the SOC...a 120ah discharge is fine for a 200ah battery as long as connecting 2 batteries will double the max discharge (and charge) rates. But I don't want to wait if I can help it...so I don't care if the BMS is larger than that.

My problem is simple: Overkill is backordered, Daly gets bad reviews...all I need OR want is a plug and play BMS with low temp cutoff. I don't want to program it, attach relays etc. I am making two batteries, each with 200ah, 12v. 4S. The two batts will be paralleled, each one with a BMS...

Thanks..so looks like I will go 2S.

I am looking at the Renogy Rover Series MPPT 40a. Although the 30a unit says it will (nearly) handle the 400w of a panels (at 12v) I thought a little more overhead could be useful.

I have an small RV van with a 12 volt battery bank, inverter, and converter (charger). I am mounting two 200 watt solar panels to the roof. Two questions: 1) On such a short run, does it matter if I wire the panels for 12volt vs 24volt? 2) If I wire them in series for 24volt, can or does the...

what are you asking for the 8?
