Charger Upgrade Question
Hey everyone. I am looking to add big battery capacity to my RV and the question of a charger upgrade has me a bit "perplexed". If you installed something like a Progressive Dynamics 9200, did you b...

Don't forget the power factor. The PD9280 spec calls for a 20a CB and 12 wire because the unit has a PF of 0.7 that adds a bunch to the "watts" (VA actually) drawn from the generator or other power source.
PF corrected converters start at the 75amp size so they can still run from 15a circuits
Use the "divide by 10" rule for the DC amps draw of an inverter. An inverter running a "1000w" appliance will draw about 100a DC.
(Except with microwaves. A PSW inverter will draw that but a MSW will draw fewer DC amps to run the same MW because it also isn't running that MW at its full power due to the MSW)
