So far, so good! The electrician found some mistakes in the original install so the system no longer imports power all the while there is charge in the battery (screenshot attached) . They installed an additional CT & Harvi for the myenergi app so that now reports real time on the overall...

Thanks.. I did challenge them about this. They're here now and they're fitting 5 optimisers to the PV1 panels and say that will deal with the imbalance. I'm not knowledgeable enough to know if that's plausible or not. 😕

Here's the overall orientation of the roof..

Now you make a really interesting and potentially worrying point, thanks. Their intention is to add panel 5 or 6 to panels 1 to 4 to make that PV1 array leaving the other 7 panels as PV2 array. As you allude to, one panel in PV1 will, at times, be making a significantly different voltage to the...

Thanks Bladerunner.. Yes, that's the correct inverter. Yes, 150v is the voltage quoted by the installer as the start up voltage, hopefully adding one of the SSW panels to PV1 will be enough to hit that voltage much earlier in the day and on much darker days too. "w.r.t. the blue and orange...

No, PV1 faces ese so is in the sun before PV2, photo from this morning attached when it was below the threshold Voltage..

So.. The hybrid inverter has a minimum threshold voltage of 150v so they are returning tomorrow to make PV1 a 5 panel array and PV2 a 7 panel array which should mean PV1 starts producing much earlier and at lower light levels, which is great.. 😊 They are also checking the consumer unit wiring...

Sorry, DC graphs attached from yesterday. PV2 starts producing 240V so I'm confused why the PV1 Voltage threshold isn't 120V as it's half the size. Instead it appears to be 150V. I'll speak to the installer today. Thanks again.

Hi Michael, Here are the DC graphs for PV1 for today and the previous 3 days. You can clearly see the voltage drop when it starts producing, as it has now today and it did on Friday. It seems to need 150V before triggering production which never happened yesterday or Saturday despite PV2...

Just to illustrate the increased grid power being used, please see attached screenshots of our meter data. You can see prior to PV we were using ~200W overnight compared with ~400W now. There are also no periods when we are just using battery power apart from brief periods when we are exporting...

Hi Michael, thanks. 1. No, the inverter CT is on the neutral tail from the meter. There is a CT on the positive tail in the meter box but that's connected to a Harvi for the Eddi. 2. I did think that might be the case initially but there have been days when PV1 array is in full sun and making...

Hi, thanks for looking at this.. PV1 is definitely connected, see attached screenshot. It generates intermittently, sometimes all day, other days for only part of the day and sometimes nothing all day. It's not generated at all over this weekend. The inverter app (Solarman) is frankly rubbish...

Hello, My first post here so thanks in advance for any advice offered. We had a 4.86kW array installed on 29th March, the panels are Longi 405W units and the array is split into a bank of 4 panels and a bank of 8 panels due to physical limitations of our roof slopes, the 4 panel faces ESE and...
