It all comes back to voltage.Learned that with the TriMetric a long
time ago. I have a dozen eVaults out there, mostly singles but one set up
with 3, all working just fine using voltage control.

For systems where the batteries are getting a relatively full charge every
week or and cycling down below 30% at least every now and then, closed loop
is certainly the safest way to go since the battery BMS is determining the
SOC, not the inverter's algorithm.
I've been told by a tech at Fortress
Ray,
Establishing CAN is straightforward. Most important steps:
-Pins 1,2,3 on eVault go to pins 4,5,6 in that order
- Update the eVault with CAN firmware
-Use protocol 6 on the battery and protocol 00 on the Sol Ark
Closed loop is an important feature that I personally wouldn’t want to pass
I've wanted to find a thermostat that could handle DC Voltage for a while now,
but I haven't done the research. What I've wanted to do is to tap right off the
PV input, through a thermostat, into a simple resistive heater. That way, it
won't drain the battery to warm the array. If the resistive
Hi Chris;
That's not for the eVault. Other Wrenches have mentioned using a pet
heating pad with a 120 vac plug in thermostat. I'm going to try that,
I'll report back to the list what I find.
Secondly, I am having issues figuring out how to do the closed loop
coms. The Fortress
Ray,
I'd suggest reaching out to the Fortress techie's as they just introduced a
heater product for their enclosure products. While I don't believe they
have a unit specif to the eVault but you should be able to make it work.
