Which BSLBATT batteries can it read?
We target BSLBATT 48 V rack and wall-mounted LiFePO4 batteries with RJ45 RS485 communication. Tell us your model when you order; we validate it before shipping.
I use a Victron system. Is that a problem?
No. Your Victron (or SMA, Deye…) inverter keeps its CAN link to the battery. The box reads from a separate port.
Does it need the internet?
No, everything runs locally. The internet is only for the optional remote dashboard.
Can it read a stack of batteries?
Yes, that is part of our tests for linked batteries with distinct addresses.
When does it ship?
On 10 November 2026, as a pre-order. If we cannot, you get a full refund unless you prefer to wait.
Can I cancel?
Yes, at any time before shipping, with a full refund including shipping.
How is it powered?
USB-C from any charger, under one watt.
Warranty?
Two years. If your model is not supported once delivered, you can return it within 30 days for a full refund, return paid by us.
Will it void my battery warranty?
It only reads data through the communication port, like the service tools installers use, and never changes a setting. Check your warranty terms if in doubt.
Is it a BSLBATT product?
No. MoniWatt for BSLBATT is an independent product designed in France. BSLBATT is a trademark of its owner.
