I have x1 CATL 302Ah LiFePO4 and x1 EVE 304ah LiFePO4. And I have x2 Daly 4s 250amp BMS's (and 3000w inverter for running AC in travel trailer). I'm going to configure them in 4s2p like the design below (Thanks FilterGuy for the great resource). Just to double check: I can put my Blue Sea...

Thanks Sunshine_Eggo and Rhino, I understand you both. I'll make sure to get a Class T fuse. I believe you are referring to a ceramic resistor to pre-charge before connecting inverter and yes I already have a 25w 30 Ohm resistor for that. Thanks again!!

Could someone please help explain in layman's terms.... Why does this generic diagram of Nate's have a 400amp ANL fuse coming off the battery bank and then also mega fuses in the Lynx Distributor? Isn't this somewhat doubling up fuses. I can understand you need a fuse to prevent arc or whatnot...

I fully agree, but the roof space on my RV will only allow certain sizes on certain areas as I have to work around vents, ac, antena, ect. So to help add wattage to my set up I'm forced to get 2 smaller (as in dimension) panels on the front roof area, which unfortunately means it has to be a...

Does anyone have a useful hack as to how I can search for solar panels by specifying either volts or amps that I'm wanting. (Trying to pair up different wattage panels.) (going to be purchasing 2 panels, but lets focus on the individual numbers...) Aiming for as much wattage as possible in a...

Yeah you're right, I was having a brain lapse with that formula for a minute there. And I've also seen people add 20% to their number after dividing. Thanks for the brain jog =)

HRTKD, you brought up a good topic that I was wondering about too. Why isn't the Victron calculator giving me the 150/70 as an option. It seems to be pushing me up to pretty high ratings with the 150/100 and no other options. The panel specs are below. REC365NP 2 specifications: Nominal power...

Copy that! He recommended I leave the 40voc stuff for home systems with 24v and 48v batteries and referred me back to 100w and 200w panels =( With me being new to this and him dealing with them everyday, I wanted to double check before I proceeded. Thanks so much everyone for your quick input.

I'm planning my 12v RV set up and wanting to go with +- 300 watt panels because of limited roof space. I've come across the REC Solar 365 watt mono panels that Northern Arizona Wind and Sun offer. My MPPT victron controller will be the SmartSolar MPPT 150/100 Tr. I read that its optimal to have...
