I have a 48v lifepo4 bank with two 75 aHr batteries wired parallel to a Growatt inverter (3000 ES). They each have a 60A Xiaoxiang BMS.
I mistakenly left my EV plugged in too long. I'm assuming the BMS shut down the system. The Growatt shut down and now the battery won't take a charge.
I disconnected solar and battery from the Growatt and then reconnected. I'm assuming since the battery bank now measures 38V I need to boost the BMS with a quick charge above 48V to wake it up. How can I do this without a 48V+ power supply? The Growatt, despite showing 235V will not start the BMS/battery.
My PS only goes to 30V
