Which Felicity batteries are supported?
We target the Felicity Solar FLB series of 48 V LiFePO4 batteries with RS485 ports. Tell us the model on your battery label when you order; we test it before shipping.
Does it work with my Felicity inverter?
The box talks to the battery, not to the inverter, and leaves their link untouched, so the inverter brand does not matter. Let us know your inverter anyway so we test the full setup.
Is internet required?
No. Everything works on your local Wi-Fi. Internet is only used if you enable the remote dashboard.
Several batteries?
Yes for batteries linked with their own addresses; give us the number when ordering.
When will I receive it?
It ships on 10 November 2026. If not, full refund unless you prefer to wait. Delivery time depends on your country.
Which countries do you ship to?
Europe, the UK, North Africa, North America, Australia and Japan. The exact shipping price appears at checkout.
Can I cancel my order?
Yes, any time before shipping, and you get everything back including shipping.
How is it powered?
Through USB-C from any phone charger. It uses less than a watt.
Warranty?
Two years. If your model turns out not to be supported, return it within 30 days for a full refund; we pay the return.
Is it a Felicity Solar product?
No. MoniWatt for Felicity is an independent accessory designed in France. Felicity Solar is a trademark of its owner.
