I’m confused.
In the GivEnergy portal i can only see a setting for Battery Charge Power on the Inverter card under Settings and Battery options. - Is this at all times ie mains charging and solar panel charging?
I want to reduce the stress while charging from mains over the 6h off peak period, but charge as quick as the panels can when charging from solar, so I don’t want to limit that. Not yet anyway.
I note that in the GE Cloud Add-On to Home Assistant I have a Battery Charge power setting and also an Inverter Charge Power Percentage - What are they? Does one map on to portal Battery Charge Power? And if so, where can I find the other in the Portal.
Similarly, in the GivTCP Add-On, I can see a Battery Charge Rate and a Battery Charge Rate AC. Same questions as above!
(Gen 3 5kW Hybrid Inverter with 9.5kWh battery)
I run an automation at 23:30 to set my “active power rate” to 50% (adjust to suit), then at 05:30 to set it back to 100%. Works a treat. Aim for 100% charge rate about half hour before finish to allow a bit of time for cell balancing and self calibration.
What and where is “Active power rate”?
I’ve taken a gamble and set “Battery charge rate AC” in GivTCP to 60%, and right now the battery is charging at about 2kW - so about 60% of the max of 3.6kW.
I could set up an automation if necessary, but will see what the solar charge rate is on the next sunny day!
On the portal if you use the remote control section (portal > inverter card > little cog in top right corner) you’ll get a bunch of setting.
In there will be charge power in % and also charge power in W
One of those only impacts AC charging (from memory this is the % one)
Same for discharge
Inverter Active Power impacts the entire inverter so will limit output of the entire inverter, including what it supplies to the house. I.e if a 5kw hybrid is set to 50% then no matter what is going on the inverter will be now a 2.5kW inverter.

This is true. Active Power Rate does affect both charge and discharge rates, but that’s fine if using it via an automation during the scheduled charge period.
In retrospect, the AC Charge Rate might be a better choice.
Ah right, I see it now. I had been there before but forgot how to get to it.
The Active Power Rate is labelled as “Inverter Max Output Active Power Percent” in the portal. My battery charged up nicely over 5h at 60% (2KW) and today when the sun came out briefly it was charging at 3kW; so that’s what I wanted.
I’m going to make up a table.
Thanks all
