WiFiXpert Compatibility Score — GivEnergy inverter & battery
Connects through a small dongle on the inverter, which is nearly always fitted in the worst signal spot in the house.
Fussy — expect some setup pain
Eight checks, same for every device. The eight numbers below add up to 56.
The eight checks
| What we check | Rating | Points |
|---|---|---|
Works on 2.4 GHz Long-range band only. | Excellent | 14/14 |
Works on 5 GHz Not offered on the dongle. | Not supported | 3/14 |
Modern Wi-Fi security Some need the router's security set the old way, which we don't recommend. | Older dongles struggle | 8/12 |
Happy on mesh Wi-Fi Fixed in place; it keeps the box it first joined. | Fair | 10/16 |
Works on a guest network Setup uses the dongle's own temporary network plus your phone. | Poor | 3/8 |
Survives a plug-in extender Extenders in a loft or garage often can't reach either. | Issues possible | 4/8 |
Doesn't depend on chatty discovery Sends readings to GivEnergy's servers. | Low dependency | 9/16 |
Easy to fix when it goes wrong Re-pairing means a laptop or phone at the inverter, often up a ladder. | Fiddly | 5/12 |
| WiFiXpert Compatibility Score | 56/100 | |
What usually goes wrong
Portal shows no data, so you can't see whether the battery charged overnight.
Free things to try, in this order
- 1
Stand at the inverter and check the signal on your phone before anything else.
- 2
Ask whether the dongle can be moved on a longer lead to a better spot.
- 3
A mesh box on the same floor as the inverter is the dependable fix.
Before you buy anything
One mesh box near the inverter after confirming the signal there is weak.
Answers about this gadget
What it needs from your network
Inverter or gateway in a loft, garage or utility room — nearly always the worst-covered part of the house.
- Bands it uses
- 2.4 GHz only on most models. It will not see a Wi-Fi name that is 5 GHz only, and setup fails silently if your phone is on the 5 GHz half of a split network.
- How it's found
- Cloud reporting, with local monitoring on some brands.
- Background discovery traffic
- Low.
- On a guest network
- Setup fails.
- On a separate gadget network
- Fine on an IoT network.
Getting it set up
- • Ask the installer to run an Ethernet cable while the work is being done. It is far cheaper then than later.
- • Check the signal at the inverter before sign-off.
- • Stand next to your router while you set it up, then move the gadget to where it lives.
- • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
- • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
- • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.
With mesh Wi-Fi
- • A powerline adapter or a wired mesh box in the garage beats trying to push Wi-Fi through a loft hatch.
