How/Why our batteries became so affordable. This guy has lots of good videos if you find this interesting.

Maybe a dumb question but here it goes!. I have some EG4 LiFepower4 batteries 48v 100ah, that have been in storage for about 4 months. It will be another couple of months before I have an inverter and solar panels ready. I know you shouldn't let the batteries sit to long without using/charging...

Currently I have an EG4 6000XP but don't believe it would be suitable for long term in a whole house capacity, but it should be great for emergencies and keeping the lights on in a grid outage. So it has me considering if I should upgrade. In looking at the specs it appears the 12000XP has...

I have a 6000xp and lifepower4 V2 batteries. I was going to get the lifepower4 communication hub, but saw it does not work with V2 batteries. Is there another option to be able to see all of the batteries and there current condition/status?

I just got an EG4 chargeverter, and am charging my rack batteries one at a time to try to get them all to the same SOC or voltage level before connecting them all together. My issue is that I cannot get coms working between the battery and the chargeverter. I've plugged the data cable into all...

All of my roofs face NE and SW. Would ground mounts be my only option to be able to face South?

For clarity, I am NOT an electrician, so this may be a dumb question. This weekend I plan on setting up my inverter and batteries. There will be no grid input and no pv input. I'll have a small panel with outlets to be able to run some things and put a load on the system. Would this require a...
