Have a Lithium Battery that was not in use during the winter and rather than remove from my Trailer I shut off using the app. Now that I am ready to use, I can't connect to the unit using my old app to turn the charge/discharge back on. There is a new app that was released, however I don't...

Have a question on the wiring for my Multiplus II 3000(AC Side) which will be installed in a tiny house. I have read multiple forums and watched every youtube video out there, but seems like there is not a one approach concensus. Wire size will be 6/3 per manual. - I have seen romex used...

A bit confused on this as I see conflicting information. Understand that the dc side needs to be bonded to the trailer, and everything on the AC side needs to be grounded to the main panel. Question is where to I ground the main panel? The trailer will be stationary and I could ground to...

Have a question on all- in-one inverters. Specifically looking at EG4 or Growatt 3k system. The installation would be for an off grid tiny house where I would like to shut off AC power when we are not there. Do these unit allow turning off AC power but still charge the batteries through PV...

I have tried searching, probably not using the correct search terms. Any suggestions on how to kick start a 12v lithium battery from being discharged to 5.5v? The battery has blue tooth monitoring built in and can't be shut off. Any Help is appreciated.

Its time to replace the battery in our alarm panel and was thinking of going lithium. The panel I have is a Vista 21p as I measured the voltage looks like the charge voltage is right at 13.7. If I hook up a lithium battery to that, I don't see how it could ever get overcharged, but wanted to...

This is probably a silly question, but if I have a router that is currently on a transformer (12v 2a) with a 2.1mm tip. Would prefer not to have the inverter on when in use, thinking I should just be able to splice into the wires get rid of the transformer and connect directly to a Battery...

I have noticed that my Victron MPPT is switching to absorption charge for my lithium battery well before what I would expect. Battery voltage is 13.2 if charger is disabled, as soon as I switch on, voltage quickly jumps to the absorption limit I have set in this case 14.4v and triggers...

Does anyone have experience with the efficiency rating on a Powermax Charger/Converter? Want to make sure I pair with a generator that will not feel overtaxed and would prefer to run at about 60% load given that I will probably be running for a couple hours at a time. Looking at the propane...

Interested in finding out what the consensus is on a backup option for charging Lithium batteries when solar is not performing/in shaded area: Options I am considering: - DC-DC charger off TV, this would be while the Truck is idle. If we are driving, not really an issue as the solar panels...

Have two Renogy panels both 160w, purchased at separate times. By themselves, each puts out 90-100 watts, but when I plug them both in, it seems to limit to 130 watts. Not really sure how to trouble shoot this, thoughts?

Just curious what everyone does. I know best practice says that you should store your Lithium batteries in 70-80F, but wondering if everyone removes from their RV/Vehicle when not in use. Seems impossible to maintain those ideal temps in most locations without removing. For reference I am in...

Have 160w Solar panel and understand that December is going to be one of the lowest output months as far as solar goes. I ran a calculator and it seems to match up to what I am seeing based on the charge controller, roughly 400w of power per day. Panel is fixed with no tilt. That being said...

Did a bit of research on this topic and wanted to make sure my thinking is correct on this as am fairly new to solar. Have a 160w Solar panel mounted on my RV. For the most part this will easily provide our power needs in AZ when we are not in a shaded area. For those other instances was...

I pulled the trigger on the Rebel 100Ah Lithium battery and am happy with the packaging and the product received, will test capacity over the weekend. I think bad experiences can happen even with a larger company like Aims Corp as one member chimed in, so I figured I would give this one a shot...

Going camping this weekend and have a 65ah battery on my rv with solar and charge controller. Thinking this would be ok, but any issues with hooking up my fish finder battery to the main battery to top it off while I have no access to ac power? Is there a better way to do this? Also have a...

Hello, New to solar and Lithium batteries for an RV, and had some questions before I move forward on my plans. I already have a 160w panel and a Victron charge controller (possibly expand to two panels if necessary - have low power requirements). Question is related to the lithium battery...
