no battery , exporting yo the grid , so if my panels are 7310KWP how much KWHr they are expected to generate?
The max the inverter can output (to the house) is 5kW. Do you have a battery? You may be able to get a bit more output if the battery is empty
I think I mixed up the 7310 KWP figure but that doesn’t necessarily generate 7KWHr am I right?
Look at your Data. Look at the DC voltage for EACH of PV1 and PV2. It sounds like one string could be dead
The inverter is limited to 5KW input to the grid. Panels will have a peak available output output of 7.3 Kw, in ideal conditions. The inverter can only harness 5KW, with a bit of headroom up to 5.3. Unless you have batteries that can take panel excess, or a hybrid inverter with an off grid branch circuit, you'll miss out on the extra 2KW during the peak window (clear, sunny, midday, summer). The advantage of oversizing is you'll maintain the grid maximum for a longer period.
need a bit of advice, I recently (last Friday )installed 17 panels 430 each, would it be right to assume that the system could generate in or around 7KW in a day provided all conditions are met?
I’m only getting a maximum of 5.3 KW ?
The inverter is 5KW as well
Are all 17 panels producing at the same time? You won't get 7kw with a 5kw inverter you'll suffer from what's called clipping. If you have a battery you can run the house from it in the night and charge it during the day.
Well a solis inverter won't let you drop below 4%. I have a weco which is good for a 100% discharge but I can only use 96% of it.
How low of a percentage can Solis batteries be used to? I'm assuming zero but maybe that's an incorrect assumption.
Just bang in 1kwp as the size, pick where you are in the country on the map with your mouse, and then see how much you get with 40deg and compare to 0 deg slope.

Another maybe silly question, I have a large featureless space on a South facing vertical wall, maybe 4m x 3m.
I saw examples of solar fences, any idea what the difference is between vertical panels and those at the ideal 35 or 40 degree tilt?
This is my one
Hi, apply for inverter control on Solis website, this allows you to remote change the basic settings on the inverter including charge and dis-charge times.
So ours charges batteries 2-6 Energia EV window, then discharges from 10.30 to just before 2am.
So far works well.
Oh and you can change charge and dis-charge current, I've not needed to change either of those.
You need automation.
You need the inverter to be controllable by Home Assistant. Home Assistant would have to be able to change the operating modes.
I don't know if this is possible or how easy it is with a Solis. It is certainly easier with a Sofar
nvm
Hi.
I was wondering if anyone can help or point me in the right direction I would appreciate it.
How can I set my Solis inverter up to dump any battery excess to the grid by 2 am in order for me to charge it between 2&6 am?
Am on the Energia EV plan.
Thanks
The majority of kit is IP65 rated. So it will happily go on an outside wall without any cabinets or heaters. Might need to be somewhat sheltered
Some battery units would not be suitable for outdoor installation - the type that go into a rack.
Are there many resources for mounting inverter and battery on the exterior of your house?
My attic is converted so there's no space, and Im not too comfortable putting a battery inside. I started looking at electrical cabinets and maybe adding insulation and a small heater if necessary.
Cool, thanks for the clarification.
Yeah you'll just see what's coming or going to the grid.
To see actual house use, you'll need the solar CT.
Ok, so I've the standard set up I suppose you could say in terms of EV functionality, correct?
And solar inclusion is a nice to have as you have a better overview of everything going on, otherwise you just see what the charger is using and what the home is drawing from or feeding to the grid, and it's generally optional?
Zappi should be able to work without the solar CT. As all it needs is the grid as it's monitoring export.
Having a solar CT is nice, but not required.
Nobody will install a MyEnergi CT clamp for Solar, unless you specifically request / order it. It is not fully mandatory for the Zappi or Eddi. Yes, the Zappi cannot function to it's full potential.
Installation was by the same company as part of the same package. Solar team spilled over a bit into the next day when the EV guys arrived so they weren't two separate installs by two different companies, so I'd expect a compete set up.
It's not that. If you want a MyEnergi CT clamp for monitoring the solar, you would have to pay extra separately for it
I took a look around over the weekend, seems like there's just the one Harvi at the smart metre. I fairness, I suppose, when the EV charger installer came the electrician setting up the inverter was still working on it so he wasn't hanging around for the day until he finished.
Sorted
unfortunately a Harvi is the first port of call for lazy installers
Post a pic of the screen if unsure, but it can't know about what it can't see.
You should have 2 X CT 's - one Grid and one Solar (on the AC live at either the inverter or the fuseboard).
CT's should be hard wired back to an Eddi or Zappi. A Harvi is a past resort when hard wiring is not possible
SolisCloud is giving me better figures than MyEnergi, albeit every few minutes.
So I'm wondering if there's a configuration issue with the Zappi/Hub. There's a Harvi in the mains electrical box so what should I expect to see in the MyEnergi app? My percentage figure remains 0 in the Green Leaf and when clicking through into the Leaf I never get green consumed gen figures, just Consumption(imported from Grid) and Generation figures.
The House consumption only shows consumption history when taken from the grid, doesn't show consumption when on solar/battery so I must be short a CT on the solar side?
