    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.

    Oh I was simply making and observation. 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.

    Parallel Wiring with Anderson Connectors

    Thanks guys. These are the batteries I am using. https://bigbattery.com/product/24v-a123-lfp-battery-box-w-bms-free-shipping/ They are using SB175 connectors, so 175amp rating. Bigbattery sells parallel wiring kits for these that are use #6 wire. I have other SB175 connectors and was planning...

    Parallel Wiring with Anderson Connectors

    The batteries I recently purchased (24v LifePo) come with an Anderson Connector output already wired in. My question is what is the best way to connect 3 of these batteries in Parallel? I have spare Anderson connectors, can I make pigtails? Can I simply connect the three + and three - cables...

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

    I am currently waiting for 3 of the 24v A123 batteries to arrive. I debated purchasing from bigbattery but was pretty pleased with the price and performance of these batteries compared to the cost of purchasing battle borns, especially for a 24v system where I would have needed at least 4 of...

    24v all-in-one ac/dc distribution panel?

    Agreed. Your going to need 12v supply often, your panel should be after the converter.

    New to the game, i have a battery ?

    Lithium Phosphate is the way to go, from depth of discharge to number of cycles to cost over time, they win everytime. If you can afford it do it.

    You can also add additional all in one units for increased capacity which is nice.

    Split phase question.

    Since you seem to know, my Hybrid LV2424 has an option for 208V when wired in parallel with another unit. Not sure understand what is for. Thoughts? Im not doing it, was just curious when looking at the manual.

    Has anyone bought from MPP Solar Taiwan seller on ebay?

    My understanding is you may have to return them overseas for warranty purposes as well.

    Has anyone bought from MPP Solar Taiwan seller on ebay?

    Considered it and then purchased from Watts247. In stock, shipped from Utah, didn't have to worry about long ship times or import taxes. If time wasn't any issue, I might have given it shot through eBay though.

    2000w, 24v solar system

    Sounds like you'd be better off with a GroWatt or MPP all in one unit to me.

    MPP Inverter Solar Charger

    Seems like the generator should be feeding the A/C input on the MPP right? No sure where the shore power fits in.

    MPPSolar LV2424 will not power up.

    How did this turn out?

    My guess is they were dropping a battery in the container and then attaching those cables to power the inverter. Now you just have an empty container. Could be useful if you plan on putting another battery there though. I would probably remove and start over.

    Big Battery A123, What to look for?

    I am ordering 2 24v A123 batteries from Big Battery, and was wondering what I should look for upon delivery? What tests should be run initially? Anything else to be aware of? Thanks!
