I am planning to have a Mitsubishi Zuba Central Heat Pump installed in my log home to replace the electric forced air furnace. the Zuba will work down to -30C. The power adjust as needed with a MAX input of 3,650W and uses a DC motor rather then AC. My long range goal is to put in solor/wind power, would the input on this unit be to much for an alternate power source?

I can't find the specs on the heat pump you've got but my rough math (erring on the side of caution) suggests you'd need about a dozen 100w panels and about 20 105AH batteries. The crappy thing about solar running your heating is that you do need a big reserve of batteries for night.

You'd have to be more detailed about what you are thinking of in terms of "an alternate power source".

Do you need storage, or can you grid-tie?

The Mitsubishi unit doesn't actually hook up to DC. The unit uses an inverter to make it from AC and the inverter is part of the Mitsu system.

My long range goals would be to install PV



My long range goals would be to setup a wind turbine as well as PV on my garage hooked into a storage system and invertor to provide power to my log home. I was looking at propane for heat but the cost of propane is to high in my area. The Mitsubishi Zuba Heat Pump provides heat done to -30C, The energy usage fluxuates as needed but has a max input of 3650 W. Only available in Canada.

a storage system and invertor to provide power to my log home

Providing power for lights, water pressure, entertainment, even refrigeration is one thing, but to have to come up with kilowatts per hour, every hour, through long dark winter nights is a tall order for a PV/battery system. It's hard to believe that wood or even propane is "to high" compared to the lifecycle costs of a battery bank big enough to handle that, not to mention the solar panels to fill it on a daily basis.

Where are you and how much does the propane cost?
