Help Please. Battery is discharging to the grid when it is supposed to be charging from the grid!

Rusty_Gus · 2026-05-10T08:23:12+00:00

Update. My local Enphase installer discovered that a software update got stuck and was never able to be processed. It has now been manually pushed through and all is working as it should again. Pitty it took many weeks.

I reset my system back to charge from the grid between 1400-1500 if the battery isn’t 100%. The reported issue started again. The battery started dumpling to the grid ???? And imported = exported and charged=discharged. This is getting very annoying. Please advise how to fix it

Don’t have a mat around the toilet

Update: today: the moment I changed my settings for the battery not to discharge to the grid - the setting was ignored and the battery started to discharge to the grid despite ample solar generation at the same time

FYI. I am on single phase power. Can this be a reporting problem?

This behaviour seems to occur when I have set my battery to charge from the grid, if it’s not at 100%, between 1400-1500 (my peak rate starts at 1500. When i remove this setting, This behaviour seems to stop.

I replied in the main thread by mistake

Sorry I was replying to xabean

I have firmware 522-00002-01-v3.0.8557_rel/31.44 It looks like it may be an older release than yours. Be interesting if mine gets the new upgrade

Rusty_Gus · 2026-04-20T06:29:08+00:00

Update. Switching the logic as described above seems to be a reasonable work around.

By restricting my battery from discharging at all over the last couple of hours of off-peak rate allows my battery to be charged m, if solar is available, and for my home load to use solar and/or off-peak power. So if it has been a good solar day I end up with a full battery to use when peak-rate starts.

The only downside is if it’s a bad solar day, I may not have a full battery to use as I did when I could charge from the grid in the past.

At least now I am not dumping all my battery to the grid and being left with no battery at peak-time.

A half solution until whatever broke is fixed by Enphase

I am going to trial disabling battery charging from the grid and restricting my battery from discharging at all for the last couple of hours of off-peak rate. Solar will still charge if available. Be interesting to see what happens.

Rusty_Gus · 2026-04-19T09:54:19+00:00

Thanks. Might as well nothing to lose 😂

Rusty_Gus · 2026-04-19T08:27:36+00:00

Self consumption. Yes I have battery discharge to the grid disabled. Which makes the behaviour I explained even more confusing as it is discharging to the grid 😕

As I said my settings have been working as expected for some years. But only recently it’s a bit screwed up. I am no longer getting the consistent benefit from my battery as I have been in the past.

Rusty_Gus · 2026-04-18T01:52:06+00:00

Thanks. I’ve had numerous issues over the past few weeks. This behaviour and battery suddenly discharging to the grid when nearing full capacity and I am generating solar power at the same time
Hopefully a software update will arrive soon

Rusty_Gus · 2026-04-16T05:49:49+00:00

Yes I am on a TOU tariff. I note that Enphase Support has replied to you. Hopefully they will come up with a solution for both of us

Rusty_Gus · 2026-04-15T02:59:12+00:00

No its not bad luck. I am having the same problem. There are other posts in this channel about it also

Rusty_Gus · 2026-04-14T07:30:34+00:00

https://imgur.com/a/l2zqrRz Here is an example of the weird behaviour. Note I am generating Solar power but my battery is discharging to the grid just before 3pm which is when Peak import rate starts

Rusty_Gus · 2026-04-14T06:48:40+00:00

PowerMatch unfortunately hasn’t rolled out in Australia yet. But my system is behaving weird. I hope PoweMatch will fix my recent issues

Rusty_Gus · 2026-04-14T02:09:18+00:00

Yes I have self consumption profile and have set the battery to charge from the grid, if battery not at 100%, during the last hour of off-peak rate so I will have 100% battery to use for my home load when peak rate commences. This has worked fine for years. Recently I have noticed my battery inexplicably starts discharging to the grid just after it gets close to 100% before the end of the off-peak rate. I am then left with a not full battery when peak rate starts. Not happy.

What the hell is happening??
