Honda 2000va should power an 1857va device just fine.
Honda is good for 30 minutes and by then the PD is tapering amps anyway.
May need 1857va apparent power however the amps will be based on the 1300 watts actual power.
Honda "2000" is not 2000VA it is rated at 1600VA and also at 13.3a (120v) where 13.3 x 120 = 1596
Kill-A- Watt readings with a non-PF corrected 75amper doing 75 amps (constant) into a battery with voltage at 14.08 (and rising) when the charger is set to 14.8v.
123.5v, 13.64a, 1241w, PF 0.73, 1693VA. DC Output 75 x 14.08 = 1056w and input 1241w = 85% efficiency. (Don't know why the VA is a tad higher reading than V x A.)
An 80 amper scaled up would be 80/75 x 1690 = 1802
It is true that some gens can initially run more than their continuous ratings. How long that would have to last depends on the charging amps wrt the AH capacity of the bank and its initial SOC. Half an hour would be with a small battery bank like a pair of 6s or a pair of 12s starting at 50%. Four batteries would be an hour in Bulk with a 70 amp charger.
