I want to use the maximum amount of energy from my battery as safely as I can, maybe for 3-4 days a week. It is a Chins 2560 Watt hour deep cycle LiFePO4 at 12.8V at 200 Amp hours. From battery maker web site: Standard charge current: 50A Charging time: Approximately 5 hours Max continuous...

Hi friends. Thanks for reading. I bought a new CHINS battery from a couple who was going off-grid, but due to personal finances, decided to scrap that plan. They sold me the battery with no owners manual and no battery bolts. It is a 12.8V 200 AH 2560WH LiFePO4 deep cycle battery. It has no...

Hello I am trying to diagnose a small DIY system. I think the panels are charging, just not certain. No expensive battery monitor. The SCC has a battery voltage on it, and I have a shunt with 2 meters connected to it - charge and discharge being monitored. The 'discharge' meter shows just fine -...

I want to add air conditioning to my house. I want it to run off solar. It can be a dc to dc or an AC powered unit. It can be a heat pump or other inverter as well - most efficient, but I'm flexible on efficiency vs price. Example: Mini-splits can be bought for $500, or they can cost $2300...

Hello and thanks for reading! My goal: charge a portable power station/generator via the sun only. I have a Grecell Portable Power Station HW01. It uses a LiFePO4 battery. It has a built-in BMS. It is also cloudy and shady where I am putting the panel. I simply want to charge the power station...
