Greetings! My old battery system needs to be replaced and I am trying to decide between a small 24v battery upgrade and a larger system upgrade. I have a separate post about finding batteries but wanted to post here now that I'm considering a whole system upgrade. Can you help me design a system that will work?
Idea 1: Replace the 4 FLAs (24v) with 1 or 2 24v 200ah lithiums. Probably EG4s. Keep my charge controllers and inverter. Cheap option but limited power.
Idea 2: Upgrade to 48v system. Replace my controllers, AC battery charger, and inverter with something like a 6548 all-in-one (recommended by William Prowse). Buy 1 or 2 48v batteries, with many more options available in this voltage. But it looks like the all in one inverters all use a lot of power 1kwh per day?) and might require me to upgrade my panel array?
I'd love to stick with my current panel array if possible. Very excited to hear your ideas and recommendations!
Thank you! Evan
Current Set Up:
4 Trojan T-105 FLA batteries (6 years old)
3, 300 watt 24v panels
