About WeCo Monitor
WeCo Monitor is made by a small team in France, the same people behind Pylon-Monitor.
From one Pylontech battery to sixteen brands
MoniWatt started with Pylon-Monitor, a box we built to see inside our own Pylontech batteries. Owners of other brands asked for the same thing; MoniWatt is the answer.
WeCo batteries come from Italy and are designed to grow, module after module. This edition lets their owners see each module as it is: its charge, its cells, its temperature and its health, at home and from anywhere, without touching the link with the inverter.
How we work
The box asks your battery questions and never sends it a setting. Whatever happens to the box, your system keeps running exactly as before.
Each box is prepared for the model you give us when you order and tested before it leaves the workshop. If it cannot read your equipment, you send it back within 30 days and we pay the return.
Everything works on your own Wi-Fi without an account. The Cloud is optional, off by default, and switched off again in one click.
Questions go to the people who design the box, in English, French, German, Dutch, Spanish or Italian. Usually within a day.
Our guides come from what we see when we read these systems day after day. When we are not sure about something, we say so.
Designed in France, then prepared, tested and shipped from our workshop there, with a two-year warranty.
Independent from WeCo
