New owner questions.

Hello,
I have recently had installed a GIV-HY5.0 with an 8.2 GE battery. I have Eco switched on and also forced charge between 02:00 to 06:00 (my cheap hours with bulb)

My ground mount panels are heavily shaded (moving shade) due to low angle of sun and surrounding trees plus shade from other panels again due to low angle of sun. Throughout most of the year, this will not be a problem but currently with low sun, it is what it is. I'm not sure if this relevant to my questions, but details. So currently they only generate between 150 to 700W per hour.

First question. As its new I spend a lot of time looking at the numbers coming in and out. It quite often seems to send excess solar and sometimes some from the battery to the grid rather than to charging my batteries. Obviously not large amounts due to my low generation but anywhere between 30 to 180 W. I'd obviously much rather that was going to the battery though! Other times it does correctly send energy to the battery. Is there something wrong with the system for it to be sending to the grid when the battery is no where near fully charged?

Second question. Often the numbers do not add up on the APP. As a made up example it will say that I'm using 500w and yet the solar is producing 240w the battery is sending 327w and its drawing 50w from the grid. So far more electricity is being supplied than what the APP is saying I'm using. What's going on here?

Last question for now. My battery outputs a maximum of 2.6kw. When using shower, boiling kettle or cooking dinner etc the excess is drawn from the grid. Does adding a second battery increase the total output, so you can do more at once without drawing from the grid or just the total storage?

Thank you.

Ulven First answer - the inverter sends a snapshot to the cloud every ten minutes. When you view the data, it's a snapshot and are unlikely ever to add up in the moment. Watch the cloud data over time for trends. In my experience, the inverters work very well and over the course of a day, the import/export (as measured by my smart meter) is less than 1kW when there is sufficient PV and battery capacity.

Second answer - see first answer. Even in "Home" mode, the updates are a snapshot of register contents every ten seconds. Response times are much better but still a snapshot.

Third answer - HY5 (gen1) is limited to an output of 2.5kW (could be 2.4 or 2.6) from battery; the gen 2 is limited to 3.6kW. Adding a second battery would only help if the bottleneck was the battery discharge rate (60A from memory for the Batt8.2), so no good for you. A second battery would help to increase the period during which you could run up to 2.5kW of power from the inverter but would also take longer to charge. The simplest way to increase output is to add a second inverter/battery.

With your system, battery max output should be 3.6kw? See if you this maximum can be set in portal under settings/battery.

Tim the inverter sends a snapshot to the cloud every ten minutes

Has this changed recently, I thought it was every 5 minutes?

Data updates are every 10 seconds when directly connected to inverter in 'Home' mode and every 5 minutes in 'Away' mode i.e. connected to portal.

thank you for the replies.

Yeah battery set to max at 2600. Its obviously the gen 1. System was several months ago, but had issues getting renusol ground consoles. (ended up with a vandervaulk ground mount in the end after repeated issues with renusol stock.)
