<br>
I have a fresh Fortress Evault installation with a Solark inverter. The <br>
batteries are indoors in the center of the house, but the customer is <br>
not there full time, so the battery is unfortunately going below <br>
freezing. What are the best options for setting up a heating system for <br>
the E Vault?<br>
<br>
Here are ideas that I have not tried, but am considering:<br>
1) add a 240 v, 1000 w baseboard heater in the room near the battery <br>
that is wired to only run off the generator. Run the generator until <br>
the heat comes up, and then hopefully after 30 minutes, the battery <br>
would begin accepting a charge.<br>
<br>
2) Add an 120 vac heating blanket under the evault that would be wired <br>
to a thermostat, but also have a relay control from the PV system, so <br>
that the heater would only operate when the sun was out, and the battery <br>
was below 50F. I don't quite know how to set this up with the Solark's <br>
load controls.<br>
<br>
I've considered some DC options, but they don't make much sense, since <br>
the inverter has to be on to charge from PV anyway.<br>
<br>
The long term plan is for the client to finish the insulation, and sheet <br>
rock, and add a gas wall heater in there as needed.<br>
<br>
Thanks,<br>
