GivEnergy inverter & battery — weak wi-fi in one room

Why does my GivEnergy inverter & battery weak Wi-Fi in one room?

The short answer

Portal shows no data, so you can't see whether the battery charged overnight. On the WiFiXpert Compatibility Index the GivEnergy inverter & battery scores 56/100, and its weakest check is "Works on 5 GHz" — which is exactly where this problem comes from. Not offered on the dongle.
