Battery level not shown

[maigrait]

Hi, Might be me being a muppet but the battery level is not shown and I get an error. From debug looks like its retrieved ok?

So:

Config-
{
"name": "SolarEdge Inverter",
"manufacturer": "SolarEdge",
"model": "Inverter",
"serial": "solaredge-inverter-1",
"site_id": "XXXX",
"api_key": "XXXXXXXX",
"update_interval": 15,
"current": true,
"accessory": "SolarEdge Inverter",
"last_day": true,
"last_month": true,
"last_year": true,
"life_time": true,
"battery": true,
"debug": true
}

(I got rid of the site id and api key for now unless you need it)

Also is it possible to get all statistics returned as default lights? In particular the currentPower PV load (shown about as 3.89).
Plus the lastYear/lastMonth on my display is really the current year...?

Thanks,
c.
