The subject pretty much sums it up. I've been running my 2x24v EG4 batteries with my Growatt 3000 24v AIO for the last year or with the BMS comms connected, but recently expanded my array and so have been taking a closer look at the data coming off the system via solar assistant and am...

I am a few weeks away from adding another 1kw in panels to my mobile system, which will give me 2.6kw total. I will wait to see what the system production looks like once everything is in place, but there have already been a few days where I am generating more energy than my batteries (10kwh of...

Looking for a simple 24v based solution for keeping my two 24v EG4 LifePO4 batteries over the winter in my skoolie. Anyone try these? Thinking of two each attached to the bottom of each of the batteries run out of a thermostat that comes on at 35 and off at 45. 4 PCS Film Heater Plate...

Starting to get cold around these parts and checked on my mobile system a few days ago and sure enough one of the low temp sensors had tripped on my eg4 lifepo4 batteries (good to know it works!) and the battery had stopped charging. I looked into heater mats and all but it occurred to me I...

Planning for the next phase of the solar install on my bus. Have 1500+ watts of panels, a growatt 3000 AIO and 10kwh of LifePO4 batteries now. Net phase is adding a mini split AC and if it performs well enough, pulling the roof top unit I have now, and adding another 1K watts of solar. I am...

I’ve got 4 extra 265w panels from a kit I purchased to install on my skoolie (rv). Besides sending them to anyone that see and replies to this thread ;-), any ideas of small projects I could use them in? I’m on a 22 acre farm so lots of room. Just need the inspiration.

I have 6x 265 watt jinko solar panels flat mounted on my skoolie. I’m running it into a growatt 3000 AIO that’s connected to solarassistant. The peak power I’ve seen is around 1.3 kw. Is that about right or am I under producing / need to make some changes?

Looking to add a victron 12v to 24v DC2DC charger to my system built around a growatt 3000. Can I just wire the charger outputs to the bus bar and call it a day? If there is power coming from AC or solar at the same time, do I need to account for that? Only thing I can think of is making...

Wondering what any of you that have a ground array do to bring along your panels? I just finished mounting 6 - 265w panels on a roof rack on my bus and have another 4 that I bring along with me when I know I’m going to need a lot of power and not have (or don’t want) access to a generator. Like...

Did a quick search and didn’t find anything (maybe using wrong terms) but wondering if anyone has done any calculations for wind loading on vehicle mounted solar panels? See a lot for residential, but they all include a 20% angle. Seems this would increase the down pressure and decrease...

Laying out an idea for the roof rack for my skoolie. Each panel will get a couple more unistrut under it with side clamps. Will this be robust enough or do I need to add more to stiffen it?

I am working through different rack designs for mounting the 6x 265W panels on my school bus / skoolie conversion. The leading favorite right now is a side mounted rack, with vertical supports of unistrut attached between the windows, supporting an angle and unistrut frame. The roof is rather...

I am retrofitting my skoolie with a solar setup and would like to use the wire that’s already run from the battery compartment to the rear where I am installing the LifePO4 batteries, AIO inverter, etc. The original build used the starter battery as the house battery, so there is a 8 AWG wire...

I need to make some final decisions on my panel configuration. I have a total of ten panels that came with the kit I purchased. They are 265W / 36.7 VoC / 9.51 Isc and are going into a Growatt 3000. I have read some things that say any 2s configs are less than optimal due to increased line...

I am slowly getting my mobile setup complete in my skoolie as parts come in. I hooked up one of the EG4 Lifepower4 batteries to the Growatt 3000 that was hooked to shore power in and my AC panel out. I left it that way over night and when I checked this morning, the battery light was red and...

Starting a thread to share the solar install I’m doing in my skoolie. Today I completed the battery box and fake wall (to run the wires behind and give the inverter more air space over head). The battery box is lined with 1/4” hardie board. The short wall has a gap of ~2” to allow DC wires to...

Just wanted to get quick feedback on my planned wiring layout for the system I am installing in my skoolie. This is from the batteries to the inverter. The 24/12 and 12/24 will come later. For now its just going to be the batteries and the inverter. Not shown are shore power wiring or solar...

I have one of these DC disconnects that came along with the kit I purchased from Signature Solar: https://www.signaturesolar.com/products/rooftop-isolator-switch-dc-disconnect I am going to end up having a roof mounted 2s3p string and a ground array at 2s2p. I need somewhere to do a final...

Did some testing this weekend with the Growatt 3000 and one of the two 24v 200 ah eg4 batteries installed in my skoolie. I know it won’t run the AC for very long, but when I started it up, the battery would trip into an alarm mode. When I hooked up the BMS Test it shows a “short circuit...

I have two 24v 200ah 5.12 KWh EG4 batteries from signature solar that I am getting ready to install in my skoolie. Two questions: Has anyone ever mounted them “vertically” with the handles / posts pointing up? I don’t think it would be an issue, but wanted to make sure before I build a simple...

I have a couple of the 24v EG4 batteries (not the LL…the “regular ones” if that matters) and the 24v 40 amp charger. I charged each battery separately before paralleling. The BMS on each kicked off the charger at 26.7 volts. I read that the float voltage was somewhere north of 28v. Is there...

I purchased the 3kw bundle that @signaturesolarrichard was selling over the holidays for a mobile install on my skoolie that includes 2x EG4 200ah 24v batteries, a Growatt 3000 24V AIO and 10x 265W Panels. For now I am planning on mounting 6 of the panels on a roof rack and using the other 4...

I purchased the bundle that Signature Solar was selling over the holidays. It has a Growatt 3000 24V, 2 of their EG4 24v 200 AH server rack batteries and 10x 265W panels. I purchased it to add solar to my skoolie. I‘ve been doing some test assemblies in my workshop before the real install and...
