I needed to add an immersion first, then they put the eddi in for me. Done in 30 mins if I recall.
Should have gone with it day 1, but I didn't realise how useful it was.
Even with plenty of generation and energy in the battery I'm still seeing import. It's in the region of 6-700Wh (0.7kWh) a day.
Is it unrealistic to expect no grid import?
Does your inverter have an option to calibrate / offset the Grid CT Clamp reading. I amended my Sofar to ensure I was exporting slightly because like that, I was seeing about 1kWh per day which was therefore 30kWh per month
The import figure of about 0.7kWh is actually from the smart meter reporting. The inverter (Solis Hybrid 6kW) is showing import but under-reporting on it. Not sure if there's an option to calibrate it.
Try selecting a negative backflow figure. Can't remember what the increments are. Possibly in multiples of 100W.
Hi Jonatha,
what inverter, batteries and how many panels do you have in your sistem? what kind of panels do you have?
tks
I'm curious too what system @Jonathan has. His under 5kwp South system out performs larger systems a lot of the year (on the monthtly stats thread). So I'd really like to see if there is anything I can do to bump up mine.
Do you have optimisers on every panel or on any? I've optimisers on 5 of 16 (flat roof that gets shade) and see the optimised ones are certain running at different outputs. So they would drag the sting down otherwise. Today one was only at 20w and another at 120w on same string (during morning shade and same in evening shade). Our installer said they tested optimisers in real world and got 20% more output on identical string side by side. I believe them. Marketing speel from vendor says up to 30% boost. But cost 70 quid each so there is a fair cost relative to a panel.
How unshaded are you?
Do split the beans on the secret sauce please :)
Optimisers are just over €41 each when I got them in ~Feb/March
Let us know if you find a setting on the Solis, I can see almost up to 1kwh per day import on a CT on the mains feed but Solis shows 1kwh for the month which is way off.
According to Solis this is normal but I call BS on that.
Try setting the backflow value to a negative value to calibrate.
EDIT: This is only for those with EPMs, which are not common in Ireland.
No secret sauce, just a south facing roof (189°) which is unobstructed. (Slight shading on lower panels close to sunrise/sunset in December).
14 * JA 345W (JAM60S10-345/MR) panels (single string)
Solis RHI-5K-48ES-5G 5kW hybrid inverter
5kWh Puredrive PureStorage II DC battery
wouldn't a negative backflow mean more import?
Two issues here - Solis is importing when it shoudln't need to, and it's not reporting on that.
Have amended my post now. Seems to only apply to those with EPMs unfortunately.
There will always be a bit of reaction time import, but there is definitely a small amount of import particularly during low usage periods. That said, it isn't terrible. I only imported 6 day units (per my D/N meter) last month.
Just goes to show that perfect S is unbeatable, and you get that on a 5kW inverter!
Yeah. I am amazed at his output. We have a tiny South roof and our numbers are wayyyy less sadly. But that's the roof we have - so am not gonna complain. We have solar now finally which is the main thing.
We can always get larger South panels in time as on its own string.
I've looked too, nothing in the inverter, nor in the meter either. Always seems to be running a slight import unless exporting and batteries are full.
If anyone has the manual for the meter, post it and can double check. As that is what tells the solis what the grid+- is.
The sofar has a CT calibration where you can tune the grid CT. I try to run mine on a slight export.
Have looked before but couldn't find anything on meter side.
Must poke at this again.. if the voltage is increased the power would go up.
Hi all.
In Feb 2022 I had to have an electrician replace some fuses in the inverter setup (one had melted). However now the panels are generating about 1/4 of their usual output. For example total for July this year was 110 kWh, but July 2021 was over 400. The panels total 3.15 kW with a 2.5 kW battery.
The company that installed the PV originally are no longer trading.
Rang loads of Solar PV companies in Dublin area today, none will touch my setup as they didn't install it themselves.
Anyone any idea why this could be happening? Any settings I could check?
What fuse did he change? Can you take a picture?
Make and model would help as well, have you checked to make sure the panels are all generating if you have more than one string?
And a screenshot of the voltage from the app would help too. In fact, if you have data from 12 months, look at the voltage from then and compare it.
Hi,
My Solis Inverter will not charge my battery from the grid at the program set time. Am I missing something?
Do you have a pic of your settings?
The electrician didn't replace the fuse - he put an entirely new meter in beside the inverter:
Not sure why Solar Voltage2 is 1.6V while Voltage1 is 333V:
Looks like you have an issue with string 2 not generating. I had a similar issue after my installation and it was a faulty fireman switch. It could just be a bad connection somewhere as well.
Your inverter is set to only generate what your house can consume at any time (LmtByEPM). It will not generate any surplus for export.
Any reason why this would have been set? Were you advised to limit export by ESBN? Were you getting issues with grid over voltage etc?
Funny enough, in winter it's reversed. Jonathan can get something like 0.5Kwhr/day with his 5Kwp south panels where I'd get 300% the output (1.5Kwhr) with my 5.3Kwp East/West panels. Weather not massively different as we're about 15Km away from each other. Never could definitively figure out the descrepancy.
I don't think there is anything wrong there, only perhaps my panels/inverter work better with diffuse light than his do, while in sunshine his ones rock on
I'm with Energia on the flat tariff, have 3.5kwh solar panels on the roof but no battery. Would anyone else be in similar position with the rates they are on? Is it worth me changing to a higher day time rate, with lower night time rate, while the solar potential is better, or stick with the flat rate?
I'm still working from home so mostly do washing machine and dishwasher during the day only. The only time I'd see this changing is when the solar generation is bad in Winter and it makes no difference to us what time of day we put anything on.
Could this be the reason Solar Voltage2 is only 1 volt?
