Well, my house there is a bit complicated. There are 3 phases 220V/50Hz coming into the house, but the guy that built the house was from the States and he also wanted 110V, so he installed a huge autotransformer (20kW) to get 2 phases of 110V, and those 2 phases L1 +L2 are connected to the...

It's called Sunsmart-10K split phase inverter. I don't know the exact model number, because I'm not at the house now. I'll only be back there mid December. But as far as I know, there is only that one model.

Interesting. My display always shows 4A when battery is full and there's plenty of solar. But what's worse, is that the charge Ah+ and discharge Ah- data never zero's out. Data will say ex. it discharged 100Ah from the full battery and then charged 190Ah back. It's always like 90Ah off per 24h.

Yes, if your solar assistant reads your shunt, but try reading the data coming from the inverter and compare that. If the display shows 4A at full battery, then the data will be way off. Just wondering if it has the same error as my machine.

Does your machine also show like constant 4 amps charging into the battery, although the battery is already fully charged?

Without a battery, it just runs in bypass mode, meaning it doesn't use any solar power, or am I missing something?

Yes, that's the one. I have the PowMr version of it. Works flawlessly so far. Just the data coming from it is rubbish. Tells you it has discharged 200Ah from the fully charged battery and then has charged it with 290Ah. It's off by approx. 90Ah within 24 hours. I am in contact with SRNE because...

Here are some original data sets from the machine: T1 shows values with full sunlight, solar power therefore covering all load and charging the battery with excess power. T2 shows nighttime, so no solar power, all loads covered by the battery T3 shows full sunlight, battery fully charged, so...

Agree. The inverter efficiency is more important, at least during the night hours. The charger efficiency is less important, as long as PV can cover the loads and fully charge the battery during daylight hours. After checking some data again my estimate of an average of 200W self consumption...

Yes, I know, that's easy, but not what I ever was interested in. I want to know overall self consumption of the inverter under daily normal operating conditions, off grid with loads on day and night and with PV on during the day.

I know what idle consumption is, but that's another topic. I was just interested in the accuracy of the data coming from the wifi module, and discovered that this data was completely wrong. I wasn't even searching for idle or total self consumption of the machine, but nevertheless was astonished...

I agree with you on the term "idle", but I was never interested in the idle consumption, because like I said, that's measuring fuel of a car standing still with it's engine running. I want to know what the overall self consumption of the inverter/charger is, while in normal daily operation. And...

Fully agree. My Victron shunt also shows 0 with occasional ups and downs of a couple hundred mA, when the battery is full. But the internal shunt shows +3 to +4 amps constantly while the battery is fully charged (and plenty of solar is available). This amperage is counted into the total charge...

What does the battery current display show, while you have plenty of solar power and the battery is fully charged? Zero amps or 4 amps?

What I also miss is a parameter for the size of the battery. The SOC% display is completely useless, when using a battery bank without communication. You should be able to enter the battery size (Ah) and synchronize to 100%, when the battery is fully charged. If the internal battery shunt was...
