A friend has an off the grid holiday house. He uses a generator to provide 240v for household appliances, and a solar panel charging 12v batteries for lighting.
They have a 240v stove (which has some internal electronics for various functions) that will run OK on the 12v system with a 12v > 240v inverter, however it will not run on the generator.
The mob that sold him the generator say that his stove must be fussy about the sine wave output. I'm aware that the cheaper generators put out more a square wave than sine, which some appliances are sensitive to. He's wondering if there is a commercial device he can put in-line after the generator that will "condition" the generator's sine wave. Any recommendations?
The sine wave may indeed be the problem, but I'm wondering if it could also be the generator not having sufficient capacity to handle the stove's current at switch-on. The generator is 7kVa, but I don't know what the stove draws. He's tried just running the stove without any other 240v appliances connected, without success.
