solar powered system for block heater

[jedjoe]

I'm wondering if anyone out there has built a solar power supply for a tractor's block heater. I'm planning on storing my tractor in a storage building that has no ac power. All I would need for power in the building is something that could run a 120 volt 150 watt block heater for winter use. So I am thinking solar panels with battery system and inverter. The battery capacity would need to be sufficient to run that 150 watt block heater for a 24 hour period at most and more likely only need to run it for 12-15 hours. Any ideas welcome. Thanks

Most block heaters are more like 1500 watts not 150 and 1500 watts is a lot to do with solar especially when it’s dark.

Block heaters on my last 2 tractors were 400 watts, but that still is a big ask for a solar system unless it's a large one.
I run my block heater on a timer for 3-4 hours prior to expected use.

whats the budget, you need to know the watts of the heater, how long your going to run it and the recovery time needed.

That's what I find also. 2-3 hours ahead of use on a simple plug in timer (rated for the heater wattage) is all that's necessary for an easy start.
Then it's warming time for the transmission.

Look at the cost of batteries to store the power overnight.

He will then think it's time to fix his glow plugs.

Glow plugs may not be enough to start his tractor if in a really cold climate. I know at -10 F my Branson struggles to turn over with out block heater plugged in for awhile.
