I must agree with Ray, that inverter was never intended to run the slew of electronics we have now. There are gadgets out on the market that may do what you want but the reliability is in question. Does this site have a genny? Using the that may get you past the issue but not solving the problem. Upgrading the inverter would be my answer too. Good luck on presenting this to your customer. Not so fun times
