Hi,
Shortly, one of our members is going to be dropping off a Sola Basic ISB 4000 va unit to me.
My understanding is that it doesn't come with plugs, nor it is in the least way water resistant.
My thinking about the wiring is to add a 30 amp RV male plug for input, and a 20 amp nylon female plug on the input side so I can easily check the input voltage.
For output I'm thinking a 30 amp female, and a 20 amp female, because I so often have only a household 15 amp supply.
Placement of the unit is also a bit of a quandary. Should I place it "just before" the RV or "just after" the shore power outlet? I'm leaning to putting it just before the RV.
Does anyone know the "trade off" between volts and amps? Is it as simple as wattage divided by voltage? i.e. 30 amps @ 120 volts is 3600, so at 110 volts amperage would be 32.72? Is there some "overhead" from the autoformer itself?
I understand the unit has cartridge fuses that are NOT replaceable by a circuit breaker. How likely am I to cause these to blow?
Fortunately I can "dial down" my input amperage using the remote on my Magnum inverter/charger.
Is the autoformer going to assist with the problem I have with some GFCI outlets and the Magnum inverter/charger?
I'm getting excited now.
Regards, Don
