Wolf said:Another thought is a BMS for your 7s45p pack. You will have to find a BMS that will handle the amperage you are requesting and also have a shunt trip or some cut off when the pack voltage is ~21V. Also when recharging you will need to be able to balance the pack and have an upper limit cutoff so you don't overcharge the battery.
He's relying on the inverter to low voltage cutout. Not an idea situation. I agree with Wolf that you should use a proper BMS to handle this instead of letting the inverter just shut off at low battery voltage. Not only can it be configured with alarms to let you know you are getting low on power, but it could also allow you to switch over to an alternate power source "before" you loose battery power. Also, it would allow you to start charging the battery back up before it become too dead.

What type of air heater is it ?
Must be REALLY cold if he needs 2000W heater at full blast the entire time
