Proved it worth today...system for sure. App...small fail.
17.3 kWh system with the A2 15.3kwh Wall installed late last September.
A few weeks ago a thunderstorm caused a very brief outage. The was a flicker but power came on. Our wifi router had to reboot. That annoyed me as I have tested "OFF GRID" and all went smooth...BUT we had power then then the grid returned quickly.
Last night in the wee hours, some drunk evidently hit a pole nearby and power was lost. Our battery was 100%. We got up today at 0500. Functioned as normal; AC running, TV, cooked on the electric cook top and I started a load in the dishwasher. Then I get a notice on my phone that should reduce load as the SOC was @ 10%! I looked and saw we were off grid. Went to power site and sure enough "Outage..cause vehicle accident and estimated up time is 0900-12PM.
I shut off AC, interrupted the dishwasher and shut off most everything unneeded to save power. As I type the sun is cresting the tree line and we are producing .7kWh and consuming 1kwh. So the system with has a SOC of 5% is now only putting out .4 kWh. Our Est. backup is now almost 2 hrs. So, this is a 100% real life system use and success. Timing helped as the sun is coming up and the day looks very nice. But we will have enough juice to get through the day till power is restored.
The fail is the APP. We should both have received OFF GRID or On Back up notifications and we did not. The only notice we had we were on the battery was the LOW SOC notice. Kinda late? But, better late than never. But, if we knew earlier we could have conserved more to keep a better buffer. I'll be letting Franklin know. And I know the APP has been buggy lately but notifications are important.
As I finish this, we have moved into the "safe from losing all power" zone! Love having this system!
Edit at 1:30PM EST
Power still out. And system is having production issues. Should have a full battery. I’m getting 0 production now. Intermittent spurts of production. Franklin support was helpful but we’re getting to the point of ridiculousness now. Dominion needs to get on the ball with this asap. And I have no idea what is causing the system
To fail.
