hello all. I am attempting to wire up an rv. I have a few high power pull items. the highest being a 1900 watt induction cooktop. I have looked at a variety of inverters.. some have two plugins, some 4 etc.. what I have noticed is that all of the plugins seem to be 1500 watts or less. Is there a model I need to look at? Can I draw 1900 watts out of one plug? lets say I had a 6000 watt inverter with three plugs.. one going to 1900 watt cooktop, one to 1500 watt insert, and one to 1900 watt toaster/convection oven.. can I do it? If not..whats the work around?
Inverter headache

What is your battery bank voltage? 24 or 48 volts ?
a 1900w cooktop will need a 2500w inverter and consume about 95 amps at 24V. Double those amps for a 12V system, and you have a fire about to erupt in your battery bay. Thats why there is no gear to do that at 12vPowerfab top of pole PV mount (2) | Listeroid 6/1 w/st5 gen head | XW6048 inverter/chgr | Iota 48V/15A charger | Morningstar 60A MPPT | 48V, 800A NiFe Battery (in series)| 15, Evergreen 205w "12V" PV array on pole | Midnight ePanel | Grundfos 10 SO5-9 with 3 wire Franklin Electric motor (1/2hp 240V 1ph ) on a timer for 3 hr noontime run - Runs off PV ||

If I wire two 12 volt batteries in series am I good? hook them up to my inverter and away we go? (these are ac plugin unit cookttops)Comment

A "generic" deep cycle 12V battery is about 85 amp hours, 40 of which are usable.
A "generic Golf Cart" battery is 6v 200ah, with about 100ah usable. 4 of them wired in series for 24V, might carry the 95A load for 30 minutes before they fail.
The next step up in reliability, is a 48V system, with 8 golf cart batteries, giving you 48V, 200ah. That should carry the (now its only 45A load) load for at least 30 minutes, maybe more.
Or a 3000 watt generator might be the easier way to power this gear.

As I have progressed on my RV project I came to the conclusion that, even with 1800 watts of panels and a 24 volt 430 amp/hour battery bank, I will still have to rely on the generator at times.
if I could eliminate the hair dryer and curling iron it would get me a lot closer to being independent of the generator. I gave it a lot of thought and came to the conclusion that I like being married.
I have gone with propane for cooking and hot water as well as giving up my favorite coffee maker for a French press and a tea kettle on the propane stove.
My suggestion would be to do as much as you can to reduce how much power you need. Use propane appliances where practical, LED lights and low power TV. When you have trimmed your energy budget as much as is practical then size your system t meet your energy budget.
I have Honda and Champion inverter generators and would recommend either one for RV use. The Honda is quiter but I do like the remote control feature on the Champion. My only gripe now is that I have to carry a third fuel onboard. . A diesel generator was not in the budget.
Good luck.Last edited by PNW_Steve; 10-05-2019, 03:34 PM.Comment
