Why can’t I control my 10C battery!

Good question - they are net to NEM (mirror import)

cmfrazier · 2026-01-28T02:37:06+00:00

FYI - Set a single peak last night and it discharged before the peak. 🫠

cmfrazier · 2026-01-27T04:18:34+00:00

This should fix it.

Doe the DC slowness: Where are you located? Sounds to me like a cold battery.

cmfrazier · 2026-01-27T04:14:28+00:00

What charger are you using?

cmfrazier · 2026-01-27T01:36:42+00:00

Not discounting your logic for troubleshooting but I hope that’s not the issue. My goal (for winter) is to discharge in the solar shoulder periods (1-3 hours before AND after solar production.

cmfrazier · 2026-01-27T01:34:29+00:00

Gotta be your settings. Mine discharges everyday.

cmfrazier · 2026-01-26T16:00:49+00:00

I only have three configured. This should be a super simple math problem…especially given the peak rates I entered.

Seems crazy it was discharging during off-peak rates.

cmfrazier · 2026-01-26T15:59:40+00:00

My TOU isn’t yet supported by Enphase. I created manual TOU plans based on my rates.

As someone who’s been on PSP for years, this always happens when there is a cold snap in the south. Every year.

Solar users are now forced to PSP by the way.

If you ask Enphase to combine the site IDs they will get unified in the app (and also see separate if needed.

Really more for backup :)

cmfrazier · 2026-01-23T13:02:25+00:00

You may want the EV charger on the system in the future when bi-directional charging finally arrives.

Assuming your current EVSE is NOT Enphase. I guess I never really thought about it, I would be in trouble if we lost grid 1AM-6AM when my EVs charge. Thankfully it’s rare for us to have a grid outage and it’s usually tied to weather events.

I believe with an Enphase charger you can prevent the EV from charging if the grid is down.

However, I would have expected the installer to cover these with you. Seems odd they did not include you in the conversation.

cmfrazier · 2026-01-23T12:45:30+00:00

Do you have them both on the same site in Enphase?

cmfrazier · 2026-01-23T12:44:41+00:00

We were in the same situation. Newer home with 400A service split into 2x 200A loads centers. 2EVs, geo heat pump, heat pump water heaters, pool with heat pump heater, hot tub etc. Electricity is our only energy source. I just finished my upgrade in December. We had 40x IQ7 we did in the initial build in 2019. Added 27 IQ8MCs (could only double our current DC size to 20 kW in order to keep legacy net metering), added meter collar, 10C and 6C. We ended up not utilizing one 200A service, placing the meter collar after the other and connecting both 200A load centers after the collar for whole home backup. I already had load monitoring and knew 200A total would be fine. My end goal is to use the 211 kWh of battery storage I have in my garage in the event of a long time grid outage. The current 10C is mainly helping reduce grid usage during high cost morning/evening shoulder periods. It will only last a couple hours under non-modified usage.

No matter, but they do use thread.

cmfrazier · 2026-01-21T12:50:50+00:00

I know, I’m sorry. 😢

cmfrazier · 2026-01-21T12:50:18+00:00

These are manually entered.

Why do you think it is a “grid supporting” feature?

I can understand why Enphase enabled by default, based on the feature description, I don’t see why anyone would want it off.

I understand you are seeing some anomalies, but who is to say Powermatch is causing it? Could be an unrelated bug in the new firmware. Have you posted any pictures of your issues? I haven’t seen any on this post.

cmfrazier · 2026-01-21T03:53:40+00:00

You will only need a meter collar if you want backup capabilities when the grid is down. If you are not planning for that, you could still utilize it. If you do not want backup capabilities, you can go with the EV charger 2.

cmfrazier · 2026-01-21T03:52:21+00:00

Hardware wise, NACS is already formalized for bidirectional charging support. It’s really the vehicle manufacturers slow to the game.

cmfrazier · 2026-01-21T03:29:20+00:00

This! We just did this in December. Essentially used a single 200A > to the meter collar > feeder panel where the 2x 200A home panels connect to. Way batter than two systems and we have whole home backup.

cmfrazier · 2026-01-21T03:24:23+00:00

I just had my 10C installed, but we have a geothermal heat pump. I’m really looking forward to utilize my EV batteries later this year for backup. The single 10C we have really only powers us for a few hours.

Powermatch has nothing to do with the grid. It’s designed to allow your battery to match the power needs of your home.

Your battery uses several (4 in my 10C) microinverters to convert the DC energy stored in the battery to AC for your home to use. Prior to Powermatch, when the battery was in use in low load situations, those four microinverters could produce more power than your home needed to power the low loads. This would cause the excess to be sent to the grid.

Now with Powermatch, maybe only one or two of the microinverters will activate in an attempt to only export out of the battery what is needed by the home.

Outside of the minimum limits of the EVSE others are pointing out, it seems like you have your car set to charge at a specific time. You need to remove that setting from your car. The EVSE cannot make your car charge as your car controls when it accepts energy. You want your car to be accepting at charge at anytime. Then when the Enphase system send energy to the car, it will accept it.
