I’ve just had the Solar over and battery installed. It spent the day yesterday discharging the battery as I was advised it would. Today the app shows power from the PV panels charging the battery which is 62% full but it also periodically send power to the grid. Why would it do that when the battery is not full? Thanks
Soenergy where are you looking? If on the portal it's a snapshot of data every 5/10 minutes, on the app and connected to home it's a snapshot every 10 seconds. How much power are we talking about? if it's less than 100w or so it'll just be the inverter ramping up/down.
You will always get small amounts of power being sent to the grid (and pulled from the grid), as your inverter tries to balance out the demand/load from your house, with what is coming from the solar/battery. These are transitionary, so if your house load stays exactly the same (which is quite rare, as fridges and freezers kick in), the system will balance after 15 seconds or so.
If you are seeing large amounts going to the grid, for long periods, then there may be some other issue somewhere (either in your installation, or your settings). Make sure you have 'Eco' set as your operating mode, and leave it like that for a few days, until you get to grips with the way it works. There is a lot for new customers to learn....
Hi! If it is only a small amount, or it coincides with switching on an appliance it is nothing to worry about! There is a slight time delay between the home suddenly asking for power and the battery being able to deliver it - just a few seconds. The graph on the desktop only refreshes every 10 mins or so, and the app screen only refreshes every 10 seconds. So if there is a demand - you get a brief flash of red on the graph - it just means that there was a few seconds discharge during that time period. If you switch on a big appliance the peak can look quite big but it is only for a very short period. The only time you could continue to see a large red peak is if you are using more power than the battery can discharge, e.g. if you put your oven and tumble drier on at the same time. The way around this, and to keep using battery power rather than grid is to use these appliances sequentially.
Thank you for your replies. Yes they we just transitory and small amounts. You answers make perfect sense.
A lot to learn I guess. Looking good though even at this time of year.
It's easy to overthink this stuff and get "lost in the weeds". Set it in Eco mode,set a Timex Charge if you have a ToU tariff and then let it get on with it.
It's the trends that you need to be aware of not the transitory minutae until you get a feel for how it works and how your household uses energy.
Had batteries charge up in cheap go period, and they immediately discharged to empty to the grid. First time ever, in 10 months. I have never set a timed discharge. Other than restart inverters, is there any else I can do?..2 ac inverters, 1x 8.2, 1x9.5.
I would probably:
Check the logs.
Reset both inverters to default settings and then reset the charge times.
Did both AC3 inverters do the same discharge?
Unfortunately inverters take it turns to be offline. Sometimes for hours. Restarted one, and problem didn't occur last night. Have the same problems mentioned elsewhere, but it works fine in the background, until discharge happened. Thanks.
