    MPP Inverter Solar Charger

    You need to figure out what your daily power needs are first and work back from there. When you know you power usage or goal, you can then build and battery bank to suit. You will then also need enough panels to produce that power consistently. Dont forget to consider that some days you will...

    Parallel Wiring with Anderson Connectors

    I was able to create my own anderson parallel cables by using different sized contacts inside the connectors. Powerwerx sells the contacts for wire sizes 6 through 1/0. For two 4 gauge wires I used a size 2 contact, which fit nice and snug and soldered up great.

    Heads Up Alert: Li-Ion & LFP prices going UP this month.

The public should expect prices to fluctuate with the market I have been nothing but pleased with my purchase from BigBattery, and chose to purchase largely due to value, availability, and ease of use. I do wish I could access the information on the BMS...

    Can I charge two different not connected battery's off one charge controller?

    I think you are better off wiring in parallel with one SCC and getting another simple battery/charger of some kind for your mobile needs. Wiring them with a y connection is just more wire length between a parallel connection when you should be going for the shortest length wire or busbar...

    24v powerwall with "New A123" cells from bigbattery.com... any good?

    I ordered 3 of the Plug and Play A123 batteries from bigbattery on Monday 10/12, they shipped on 10/22 and were delivered to me 10/24 via Fedex. They were well packed and appear to be well made. I have attached some photos of the way the arrived and the BMS. I did a capacity test on one of...

    Big Battery 24v A123

    Thank you good to know. It has a BMS but there is no monitoring that I know of. I was unsure when it would cut it off.

    Buyer beware big battery A123s

    I purchased 3 of these and have only tested 1, but all three have charged to 28.8 and held 28.6 after resting. I am new at this so take it with a grain of salt.

    Sizing an array for MPP Solar LV2424

    I think 3s would be pushing it especially if cold, and if the mpp doesn't charge from 115V+ then not sure what your gaining.

    Parallel Wiring with Anderson Connectors

    Thanks, I think I will use the 4awg I have to a busbar and 1/0 from there to the charge controller. Seems like that should be more than sufficient.
