I have a travel trailer with 1kw solar, 2x 202ah 24V LifePo4 batteries and a Growatt all in one inverter. The original 12V SLA battery that came with the trailer is running the 12V power in the trailer. This 12V battery is being charged by the trailers original converter powered by the 120V...

I am leaving tomorrow morning for a two week trip with my travel trailer. I am trying to get the betteries charged but the Growatt is only charging at 15a. I have two 24v batteries made with 202ah LifePo4 cells (overkill BMSs), growatt 24v spf 3000tl and 1000w solar panels. It was charging...

I have a 3000w Growatt in my RV, with 8s2p LiFePO4 batteries and overkill BMSs. I currently have the charge settings set to absorb 28.2 and float 27.2. The batteries are kept at full charge by the solar that is always on. I am reading that when the batteries are not in use for long periods of...

I recently installed a 24v Growatt all in one inverter in my RV with LiFePO4 batteries. It works great. I am thinking of putting a similar system on my house. I have a 2017 built home in the Phoneix AZ area. MY house is all electric so it uses similar energy in the summer and winter, on...

Anyone know if this is a problem. If it is what do I need to do.

I have 8s2p with 202ah LiFePO4 batteries. How do I figure out the maximum charging amps?

Growatt 24v 3000w. I have 8s2p 202ah batteires. Can I get some help with a few settings on the growatt. #2 max charging - 60a. Can this go higher for the batteries I have? #3 input voltage - GEN. Will occasionally plug into a 120 shore power and occasionally a generator. #11 Max...

Growatt 24V 3000W 8s2p 202ah LiFePO4 battery Any comments, find anything wrong.

I just completed a 24v 8 cell 202ah LiFePO4 battery. I got the BMS hooked up and I can connect to it via bluetooth. I can read the configuration from the BMS but it is not working correctly. See the following screen shots. What's wrong?

Im looking for a 24v to 12v converter for my RV. I am thinking of this one. Click here Is this a good choice? My RV fuse box has two 40a fuses, see photo. I assume this is a 40a fuse box? It is fed by a 6 awg wire. Can I keep the 12v Lead Acid battery that came with the trailer on...

How does this look? Are the wire sizes and fuses correct? Any comments?

I am planning on making a compression case for some 270ah cells. Would using some double sided kapton tape between the cells be a good idea to isolate them and help keep them from moving? Or is nothing really needed?

I have 16 272ah cells on order from China, a Growatt 24V SPF 3000TL LVM and 1000 watts of solar in my RV. I am looking for help deciding how to hook the new batteries up and what BMS(s)to get. Should I make 2x 8S batteries with two BMSs or 1x 8S2P battery with 1 BMS? What BMS(s) should I get? I...

I am looking for a generator for battery charging in a RV with a Growatt 24V SPF 3000TL LVM and two 272Ah 24V LiFePO4 batteries. 60 amp charger x 24V = 1440 watts. Does that mean a 2000w generator is good enough. It wouldn't be used very often and size and weight is a big concern for my...
