Hi everyone,
I have 2x Growatt SPF 5000 ES connected in parallel set to charge from both the PV and the utility power (when available)
I live in a country where the power utility is available 3-5 hours/day (1-2h in the morning, 1-2h in the afternoon and 1-2h in the middle of the night).
During the middle of the night, my batteries run out of power and are turned off since my cutoff voltage is set to 44V and the utility is not available to recharge the batteries.
After this, when the utility power is back, one of the inverters (the host) goes on to start recharging and giving power to the house while the other (slave 1) either never goes on or takes sometime before starting again.
My questions is why doesn't the other (slave 1) start directly with the host and why wouldn't it start at all?
