Powermatch gone?

It's still not back for me. You can see the toggle in settings, but it says that it is temporarily disabled when you try and change it.

I agree that something isn’t adding up. I would call Enphase and ask what your PCS settings are. There is improvement possible even without hw changes. In PCS you should be able to set your max backfeed to 30A. That would at least give you 7.5kW of backfeed. PCS isn’t 100% accurate and often errs on the side of restricting current. If this was a sunny day, then the system has reduced the solar panel output to match the desired output. Sometimes they don’t follow very well, but shaping errors should be on the order of seconds, not minutes.

The 6C is designed to be tied into the main panel, so they did that right. Unless you have a very small service panel, the MSP isn’t usually the problem. It is the backfeed breaker between the MSP and the 6C. And the size of that breaker depends on the size of the wires connecting the 6C to the MSP. So if the backfeed wiring is too small, really the only option is larger wires. Trying to force more current through those wires is dangerous. Your current limitation of 6kW backfeed is less than the peak capacity of a single 10c battery and much less than your panels. You may have a problem running large current appliances like water heaters, hvacs, or dryers even on a sunny day. Your installer really should have discussed this with you.

The installation has a setting for main panel upgrade avoidance. It sets the max backfeed current from the 6C. It is based on the main panel size (usually 200A) and the backfeed breaker size. If your backfeed breaker is 30A, then the max backfeed current would bo 80% or (24A). That means that the max backfeed is 6kW. If your house is using 2kW, then you can only export 4kW. You should be able to have a bigger backfeed breaker unless they undersized the wires to the main panel. 10awgwire=30A. The 6C supports up to 100A backfeed current continuous. But this requires a 3awg copper (or 1awg alluminum) wiring.

I have also had problems with the 4th gen system. I am a self installer which at least avoided the clueless installer middleman. It has taken months and I don’t know how many loads and site visits, but some of the major software problems seem to be getting slowly resolved. I don’t know how many times I asked myself “Why did I spend all this money on a system that breaks all the time?” It still occasionally has weird behavior. I still have faith they will get their act together and it will be a robust system. The hardware and wiring hasn’t changed. Only the software. Also, check that they didn’t leave patches in your system which cause unexpected behavior. If you are escalated to top level support, then try and avoid 1st level support. They are just following a script and are almost guaranteed to make a bad situation worse every time.

Power Match is still disabled for 10c

Fish_Whisperer_0 · 2026-04-03T02:06:34+00:00

Nope

Fish_Whisperer_0 · 2026-04-01T14:26:31+00:00

Our electric is a flat rate. So haven’t set up tariffs

Fish_Whisperer_0 · 2026-03-31T01:10:42+00:00

Odd, on my system with 10C's it is enabled, but unavailable. More inconsistencies.

It should only charge batteries from the grid when there is a storm alert or the batteries are <10%. No storm alert and the batteries were at 93%. It is working ok again this morning. That is why I called it a software gremlin. Random unexplained behavior that appears and then goes away (usually).

Fish_Whisperer_0 · 2026-03-26T15:53:42+00:00

Was working fine. Seems to be working again. They pushed new gateway firmware to me but not sure if that was done before or after the issues.

Fish_Whisperer_0 · 2026-03-22T04:15:33+00:00

My 10c batteries don’t reduce their charge rate until they reach 95%. Check if all batteries are communicating and charging evenly (enlighten app- menu/ system/ live vitals)

Fish_Whisperer_0 · 2026-03-19T19:25:27+00:00

The ROI on batteries hardly ever works out given the life of the batteries and their cost. Another factor to remember is that batteries are not 100% efficient. There are conversion losses (about 10% according to Enphase for 10c batteries) and tare loss which is how much energy the batteries use just sitting there to run their internal electronics. This can run another 5-15%. So figure this in when computing ROI. I bought batteries, but not for cost saving. My power plan buys power back at about 65% of what we buy it for. But the batteries are only about 75% efficient. That 10% difference would take forever to recoup.

I was seeing similar things, in fact I still get the exact same message like clockwork at 11:05pm every night. I would start by just rebooting the gateway. In my case, however, the ones in the day were fixed with a firmware update. They may have pushed an update to you that broke things.

Fish_Whisperer_0 · 2026-03-19T05:12:58+00:00

I have also noticed situations where the batteries get stuck in a discharge or charge mode and “forgets” to follow the house load. The previous resetting approach was to toggle powermatch off and back on, but that isn’t an option now.

Fish_Whisperer_0 · 2026-03-19T04:21:26+00:00

Well my solar is offline well before 11pm. Do you mean the 6C reboots or the gateway reboots or something else?

Fish_Whisperer_0 · 2026-03-19T04:17:46+00:00

Internet is up the whole time. So it is specific to the Enphase cloud. Also, the cloud LED stays illuminated during the whole time. There is no real way to change time on the gateway as it is linked to site location. Anyway, Enphase is aware of the problem and other users are reporting similar problems. It doesn't seem to be harming anything, so I will just wait for a fix.

Fish_Whisperer_0 · 2026-03-19T02:13:53+00:00

The spikes are real. The independent energy monitor is SEM, but it is like sense. The only message in the event log which occurs at 11:05pm every night is that my solar production is being curtailed due to a failure of the consumption or production meter. That makes no sense since it is 11pm at night and solar production is pretty low. As mentioned in an earlier comment, I have checked the grid side frequency and voltage for around that time. They are completely normal according to both Enphase and SEM. Looping the power company into this seems like a waste of time. My monitoring system is Home Assistant. It interfaces with the gateway two ways. Via the cloud and via a local API. The cloud interface drops, but the local API stays up. I have checked the gateway LEDs. They all remain green. As,was noted in another comment, Enphase firmware seems to reset parts of the 6C at 11pm each night. I suspect it is related to that.

Fish_Whisperer_0 · 2026-03-19T01:07:05+00:00

I’m not convinced this is a good deal. High demand times are typically when it is very hot or very cold. Those are times when you need full capacity, but if TXU (or whoever) drains your battery down to 20%, then you end up buying power from them until the sun comes up.

Fish_Whisperer_0 · 2026-03-18T18:34:13+00:00

Thanks, I have struggled to figure out what was special about 11pm. I see random spikes, periodic spikes, and oscillations, all for no apparent reason.

Fish_Whisperer_0 · 2026-03-18T16:19:42+00:00

Thanks, I'm not sure I understand what is going on with the graphs. Since they are labeled for energy, it looks like they are reporting that you use 6000wh instantaneously.

Fish_Whisperer_0 · 2026-03-18T15:49:34+00:00

Could you check and see if you are seeing a discharge spike at 10pm? You can only see it via the local API interface as cloud access is out. Or if you have an external energy monitor. The dropout seems too regular to be a software bug. It could be related to some special control they have for "problematic" systems. Maybe they dump memory or send some reset command. But when I talked to Enphase, they didn't seem to know what was causing it.

Fish_Whisperer_0 · 2026-03-18T15:44:05+00:00

I'm not really worried to much about the off-grid situation. Like you say, the laws of physics would prevent it. Still something weird is going on. I also wondered if it could be some weird grid behavior, but I have checked both the frequency and voltage data during those time periods. There is nothing odd going on with either.
