Question for you experts- Rule of thumb is to disconnect panels before disconnecting batteries. how is a BMS that disconnects battery in a cold temp situation, over voltage etc any different than disconnecting batteries and leaving panels connected to do a battery swap?

Did not know this. Thank you for the info.

Hi all, I’m looking to switch to Lifpo’s. mom torn between the valence batteries used or new battleborn s. Any suggestion between the 2? I tend to lean towards battleborn because of them being new and warranty. My other question is charging. Most of my charging is with solar and MPPT, what I...

Also, I do not have room for more than 2 6 volts that’s why I am running 3-12v.

Evening all- I currently have 3-27/100 ah flooded batteries from bi mart purchased about 9 months ago. They are not holding up very well. I’m looking to switch, I’ve always had good luck with les schwab rv deep cycles. Any other mild priced battery for a weekender that uses trailer about...

That’s not a bad idea on the timer. I think if I go lifpo I’ll mount in compartment. It would shorten up wire runs to inverter also. Just hate giving up space.

I was wondering about these, most are 15 watts each. Wonder how well it would actually work. Could easily run them off a thermostat

All, while I appreciate the ideas on how to reduce my consumption that’s not what I’m looking for. I don’t care so much about my consumption. If my batteries get low I’ll start a generator. We are part timers that boondock a lot while riding in the woods or at the coast. I am starting to...

Appreciate the input, usage isn’t my issue as what I have now works well. Especially after I install my additional panels and new controller. Currently I only have one 160 watt panel and a 30 amp PWm that came w the trailer. Winter time I do have to use generator a few times to top off but...

To answer the question about heating the batteries, I currently could not without a lot of modifications and custom boxes. I never thought about it till you mentioned it, with the lifpo I could mount in the compartment since they don’t gas and keep them above freezing.

They actually aren’t to bad overnight, I have to check it accurately once I get my monitor installed. I know the tv is minimal, blankets typically get turned off half way through the night. I think my furnace is biggest draw, I’m not worried about the usage or capacity so much. Just wanting...

So in order to not give up the luxuries what your saying is LA, gel or SLA is what I should go with? Currently using LA and it works, just want to upgrade this spring/summer.

Morning all, I am reading through a lot of your threads on different lifpo batteries and the question came to mind for someone that camps all year in temps from 80-90 degrees and down into the 5-15 degree nights in winter would lifpo be a good choiceor not with the cold temp cutoff? The...

I am currently setup with 3 LA batteries in my toyhauler. I am adding more solar and new controller, I know I can change parameters on that for lifpo, what about the built in converter that trailer came with, charging while driving off vehicle? Do say the battle born batteries require a...

Unfortunately I would need a new inverter or a 400 amp converter. My 2000 watt is a 12v

Thanks All. It sounds like my setup will fit my needs for now. Appreciate the info!

What can I expect to lose efficiency wise if I go to 24 v output and use a converter for my trailer loads?

I have 3-group 27 deep cycles. 100 ah each.

I shall find out. They are cheaper deep cycles, but if I kill them it is a forced upgrade that the wife can’t get mad about.

Thanks for the info. We are in Oregon, all of our camping is from Southern Oregon to Northern Idaho. Most of the time our exposure has some trees and shading. I am installing the epever 40 amp. I believe it will be safe for my application. Excited to get it installed and working.

So the 40 amps is the output of the controller and not the max input? Would I be better off having 2 parallel panels to my 30 pwm and a set of series to my new one to use all of my available output of the panels? part of me is thinking since they are flat mounted in a rv I’ll never see 56...

Afternoon all- I am wanting to double check and ask a question on wire sizing and amperage. currently I have 1-160 w panel on my roof with a 30 amp pwm controller 10guage wire coming in from panels, and going out from controller. I am adding 1 more 160 w panel in series w my existing, also...

Yes, battery bank is 12v. Thanks for the help.

Sadly they aren’t SLA, old style lead acid. Batteries are the next thing on my list after I get solar in and wife off my back. Batteries are brand new though and contacts are clean. They are cheap batteries for now as my originals that came with the trailer failed early from what I suspect...

I ordered the rich solar 160 and 2 180 panels. Charge controller is the epever 40 amp mppt. Also have the Renogy 500 amp monitor coming to install with everything.

Copper wire, copper terminal

2/0 wire. Size of my thumb.

I have the same cabling from battery to battery as I do to the inverter. I also ran the inverter pos on one battery and Meg on another to try and help balance the draw if that even matters?

I am adding to my solar on my trailer. I have ordered a 2nd 160 w panel to go with the one I currently have, I also ordered 2-180 w panels to wire to a new mppt controller. can I bypass my current pwm controller and run all 4 panels to my new controller to gain efficiency? I would like to do...

Thanks for the info. That explains a lot. I always knew microwaves were a little different than any other appliance but didn’t know those numbers.

Hello, new here. I am not new to solar and rv systems but far from an expert. I have a toyhauler that came with a 160 watt panel, 30 amp pwm, I installed a 2000/4000 nature power pure sine wave inverter with 3 100 ah 12v flooded batteries. I know my panel is way under sized, we don’t run...
