Hi all,
I am planning to use some excess panels for space heating.
I know that solar hot water panels would provide more BTU's per sq.ft., but I already have these PV panels and I want to put them to use.
...... Ducking and running for cover
At .80c per watt and being excess panels, I consider this a useful energy addition where I need heat.
Here's the scenario:
I want to push some solar heat into my remote cabin during winter. My other cabin energy needs are taken care of.
The plan is to mount 5 X 220 watt (1100 watt total), 24 volt panels on a pole beside the cabin and feed a Xantrex C60 load controller to a very small battery bank.
The diversion load circuit on the C60 would be connected to a wall mounted (Cabinet enclosed) 1000 watt diversion load resistor.
The idea being that the very small battery bank would charge up very quickly each morning (nothing is connected to it, it just acts as a voltage clamp for the system), and the C60 would divert full power to the 1000w element as long as the sun is shining.
I am having trouble finding out if the C60 load control circuit can divert 46 Amps to the heat resistor on a cold clear sunny day ?
(5 Panels X 220 watts / 24 vdc = 46amps)
Has anyone had any experience using the C60 as a load controller for loads of 40 - 50 amps ?
PS: If anyone has an alternate way of turning 1000 solar watts
into space heat I would be be most interested to learn about it.
Many thanks
