Hi, I'm looking to build an emergency portable solar power backup system. I'm thinking: 1. 1kw solar panel 2. 24v 3. 8x 3.2v prismastic cell 280ah 4. 2-3kw inverter So far, I'm looking at different BMS solutions. Will this work for my purpose...

Hi, I have 8x 280ah LifePo4 coming to build 24v battery. I got the Chargery BMS and didn't realize I need to use relays to charge/discharge. Is there any tutorials on this? Are relays required to get this setup going?

Hi, I'm setting up a solar generator 24v system with MPPT controler that takes up to 140v. I have four 290W panel each max 32v. What is the safe voltage to use? Should I do 32v x 4 in series to get 128v or do 64v with parallel?

Hi, I'm looking to sell a brand new Chargery BMS BMS16T-300A and the relay delay board. The item is brand new just received from China. I'm selling it because I'm no longer building a solar system. Looking for $145 USD for both item shipped within US and Canada UPS standard. E-mail fafafa888...
