Pylon-Monitor V3 Premium – Pylontech Monitoring, Dedicated Board & Colour Screen
Compatible with low-voltage Pylontech batteries fitted with an RS-232 Console port: US5000, US3000C, US3000, US2000C, US2000B+, UP2500 and the Force-L1 family. Up to 16 chained batteries, mixed models included, monitored individually from a single device plugged into the master battery — every cell included.
Since firmware 2.8 it also reads high-voltage Pylontech packs (Force H2 towers, H48050 / H48074 modules behind an SC0500 controller), detected automatically. The controller reports no state of health or cycle count, and this support has not yet been confirmed on a customer's high-voltage pack.

Frequently asked questions
- What is the difference with the Pylon-Monitor V2? Same functions and same dashboard; the V3 is built on a factory-assembled dedicated mainboard, with WiFi that reaches further, a protected battery port and a slimmer black case.
- Is there a version without a screen? Yes: the Pylon-Monitor V3 Premium Lite, same build, no screen.
- Does it work without internet? Yes, the device runs locally on your WiFi network.
- Does it void my Pylontech warranty? No, the Console port is read-only and never changes how the battery behaves.
- Can I use it with several chained batteries? Yes — up to 16 batteries (every cell included) from a single device.
The Pylon-Monitor V3 Premium reads the state of charge, voltage, current, cell health (SOH) and temperatures of your Pylontech battery in real time, straight from its Console port (RJ45). Same functions and same dashboard as the Pylon-Monitor V2, built differently: everything sits on one dedicated 4-layer mainboard, factory-assembled and inspected — zero wires inside.
Its WiFi reaches further (antenna kept clear on the board edge), its battery port is surge-protected, and its 1.8" colour screen with adjustable brightness shows the battery status at a glance. All in a premium matte-black case with a gold logo. Plug & play in under 2 minutes, no app, no account, no subscription. Designed and tested by our partner pylon-monitor.com.
Recommended uses
Ideal for installers and demanding setups: a Pylontech battery in a cellar, garage or plant room far from the router, where WiFi that reaches further makes the difference. The colour screen shows the battery status on site; the dashboard and Home Assistant show it remotely.
