You invested in an inverter.
Now protect it and keep the proof.
TENA sits in your distribution board, protects the equipment that matters, brings it back only when the supply is safe, and keeps a timestamped record of every supply event at your home.
The conditions that damage your equipment are invisible until they have already cost you.
Your surge arrester is spent
Surge arresters fail silently. Yours may have been protecting nothing for a long time, and you would have no way of knowing.
Power comes back badly
After an outage, appliances restart the instant power returns, whatever state the supply is in.
No record when you need one
If something fails, you can only describe what you remember. Nobody can show what the supply did.

- It happens againA dead surge arrester or a bad restart pattern is still there.
- You are warnedA failed surge arrester is flagged as soon as it fails, free for as long as the device is installed.
