I am building a windmill and currently have a 600 watt, 120 Volt DC Motor, 1/2 HP.

My ultimate goal is to use a battery to invert power to run my Pellet Stove when the power goes out. The Pellet Stove has a max. wattage of 440 W (Start cycle + test).
The start cycle for the pellet stove is 340 watts and the normal run wattage is 255 Watts.

I need advice on what i need to for a charge controller and dump load configurement.

Ultimately I would like to use this as my power source for the stove and recharge it off my wind mill.

Will this work and if not what would you recommend?

Thanks
Dave

Hi Dave

I thought it was a link to your pellet stove.
The inverter on the link has a lot of bells and whisles that i see as glossy junk if you dont need them.
I think if you want an inverter buy an inverter, if you want a compressor buy a compressor, not a compressor that thinks its an inverter.
But thats just me and my thoughts.
20 amp/hour battery is rather small for a backup supply and would be hardly worth builging a generator to charge something that small.
400 watts is a small inverter in my mind, as what one starts off with the intension of running often gets bigger if you have the choice.
Then again the bigger the inverter the bigger the battery capacity and so no. Where do you stop??
These are just my thoughts and i am sure other members will give different views.

Welcome to the 4M.
Pete.

Hi Pete,

the website is: www.canadiantire.ca

The product is the Motomaster Eliminator Power Box 800.

Some info. I could cut and paste:

Completely redesigned to deliver greater power for longer periods of time and to increase durability and rugged appeal

Three household outlets to power up to 600W of appliances and electronics simultaneously

Long-lasting endurance: 28 Ah power cell

Integrated AM/FM radio and alarm clock to keep you informed during emergencies or entertained during recreational activities

Also features boosting capabilities, digital power display, safety light and plug-in-and-forget charging

Includes booster cables, AC charger and 12V socket cable

Hi Pete;
Thanks for the help so far. I do not need the the Motomaster Power Box 800 with the additional bells and whistles, it was just a convenenient source of transportable power.

What size inverter would you recommend?

Inverter size and type is a personal thing that best suits your needs.
I dont like driving things to their max. upper limits.
To me a 1000w inverter would be a starting point but then that increases price range etc. and might be more than you require.
I would rather something that i could use off any 12v battery rather than rely on an internal built in battery that might fail when needed most.
If you want a selfcontained unit have you considered a computer ups supply.
It might be cheaper.
I used one for some time as a portable supply and added a plug that i could plug a external battery into.
It was ok but still a toy from my point of view, but i had it sitting there doing nothing so put it to use.
