Review on 🌞 High-Efficiency 50 Amp Solar Charge Controller - 48V, 36V, 24V, 12V Auto-Switching, PWM Panel Voltage Regulator for Lithium-ion, Lead Acid, LiFePO4 Batteries by Tom Reid

I bought this charge controller as a backup. I've had it for about 6 months and decided to split my arrays into multiple chargers and installed these last week. This failed and it keeps showing error code EO1. I tried to reset the error and it didn't reset. There are no error codes in the small manual that came with it. I completely removed it from the system and it still wouldn't reset. Don't waste time, get a slightly better product.
