Doing a solar/battery test today. Immediately after flipping the mains off the roof-top microinverters all went into a 5-minute shutdown. No impact to the IQ8s in the battery, they stayed online and the system switched to battery-backup with a hitch. The battery was at 60% when the test started, the image to the right shows it's currently charging up on sunshine. Received a text from Enphase (probably on the 15 min data push) that it was off-grid and based on the last 24 hours of consumption it would last 6 hours & 33 min with no solar. Received an email message shortly after that (probably when the client synced). The email had a few links, one was the light-blink codes. |
I keep my router on a UPS, it doesn't take that many watts to run but it ensures any inverter resets don't leave an internet outage too.If that had happened in the first 90 minutes, my internet was still up and it could have happened with almost no loss of production.
CA Rule21 201902 VV VW FWGXMnow what Grid profile are you using now?
I had a UPS for my router and main office PC here, but it croaked, and I have not gotten around to replacing it. I tried a new battery, but it quickly died as it is not charging at all. I have not had a UPS live long enough to actually help me on a real power failure. That makes 3 now that bit the dust.I keep my router on a UPS, it doesn't take that many watts to run but it ensures any inverter resets don't leave an internet outage too.
Nuts... forgot to test Foghorn ... since it's not using an "approved" API they can change it any time and might have. Well, tomorrow perhaps...lots going on (see Dang PC).Doing a solar/battery test today.
Enphase responded to my IQ8 question:"Dark Start" can be a major issue with an AC coupled only system....
This makes sense since they can provide power without batteries. This is probably the best/cheapest solution for me and I've been waiting for the IQ8's to put another 6 panels up (supposedly they don't impact the encharge limits like the iq7s do, see page 10).Yes, the IQ8 is grid-forming, so they will recharge your Encharge batteries.
I followed up with a question asking where that setting is. The minimum reserve setting on enlighten is for on-grid, if you go off-grid the system will drain below that setting.Yes, the encharge batteries can be maintained at a minimum SOC of 10 to 30% and stop discharging when their State of Charge (SoC) reaches 10% . Once the PV power is back the micros start producing the power.However, the algorithm follows an exponential timeout between restart attempts. To make this attempt successful system owners must turn off all loads in the home to ensure that a microgrid can be successfully formed and batteries can start charging.
Currently, the Very Low SoC is set at 5% and you cannot change it. But the good news is: we are working on making it configurable....... we plan to make it live in February next year.
Unamusingly, a different battery hit the low SoC threshold this morning. I'm going to reset the mode to 100% to get them all recharging.There is an ongoing issue where battery charge suddenly drops on certain batteries at times. Our Engineer team is already working on it and they are trying to fix this.
I'm 99% certain the problem is the self-consumption of the Encharge isn't be accounted for in "savings" mode. Even if it's only a few watts, over weeks it adds up. That's one of the reasons I didn't do anything this time other than report it, was pretty sure another would go a few days later.That is certainly an odd one.
Considering the expense if it happens when you're not around to manhandle it, might be well worth having one. Either that or use a thermostat to activate a relay to flip the mppt off....Worst case, I could put a small space heater near the battery banks.
Curious whether you see this behavior for http://envoy.local/production.json as well?Looks like Enphase has modified local access, requests like http://envoy.local/api/v1/production/inverters now returns a 301 (Moved)
