@kezo so what he’s offering can’t give me what I’m looking for, I can’t fully charge the 45kwh in 5 hours? That makes it a no-go then I will give him the news tomorrow. Thanks Kezo
According to the manufacturers own spec sheet no. https://dyness.com/dl5-0c-low-voltage-storage-batteries-household-use
Fogstars quotes in their FAQ’s or blog, an inverter charge output of 90-100 Amps will charge one 15kWh rack battery in around 3.3 hours. Like Dynes, Fogstar rack batteries have a 100A max charge, so multiply that by 3 equalls 9.9 hours, roughly what I said in a previous comment. The 15.5kWh/s you plan having battery has a Pace BMS potentially capable of pushing out 200A.
In the future once you have your solar connected to the battery/s and with the help of off peak charging your battery will likely charge to its full potential. Then strictly speaking you can’t output more than 16Amps to the grid without permission from the DNO.
It might help understanding by searching for DNO G98, G99 and G100.
