I currently have a 24v system with 4 LiFePo4 batteries in a 2s2p configuration. I am thinking of getting a 48v system. I would also like to get 4 more batteries for a 4s2p configuration. My current batteries are a bit shy of a year old with moderate use. If I get the same brand/model of...

I have two LiFePo4 batteries wired in series (24v, 100Ah) and I am getting two more to wire in series and then parallel (24v, 200Ah). I came across a diagram that shows two sets of batteries wired in parallel and then in series. So I would describe the two setups as 2 in series and 1 in parallel...

Looking into the MPP LV2424 (MPPT). Assumed it would be able to charge from shore power and run the inverter off the batteries at the same time like most units sold today. Then I read this in the owner's manual: " 12. NEVER cause AC output and DC input short circuited. Do NOT connect to the...

Seeing some posts about using a resistor to pre-charge (the capacitors?) the inverter. I have an MPP 2424LV-MSD that I hope to have batteries for in the next few days. I have seen lots of differing opinions on the subject. I read in one place that if the inverter is small, under 3000 watts was...

Using 6 100 watt panels, all exactly the same, can I hook 2 panels in series, then in parallel with 4 panels in series or will that give me less performance than 3+3? I'm familiar with series/parallel, but I always see each side with equal number of panels. Thanks for any insights.

I recently read a post where the person added another LiFePo battery to his system and another post responded saying that if you were charging the one battery with 30 amps that now you should now use 60 amps. Is this true and what is the reasoning?
