Pylon-Monitor V3 Premium Lite – Pylontech Monitoring, Dedicated Board, No 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
- Can I add a screen later? No — the case has no screen and no cut-out for one. If in doubt, choose the Pylon-Monitor V3 Premium, identical with a colour screen.
- What is the difference with the Pylon-Monitor Lite? Same functions; the V3 Premium Lite is built on a factory-assembled dedicated mainboard, with a protected battery port and a black case with gold logo.
- 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 Lite keeps the V3 Premium build — one dedicated 4-layer mainboard, factory-assembled and inspected, zero wires inside, protected battery port — without the physical screen. It reads the state of charge, voltage, current, cell health (SOH) and temperatures of your Pylontech battery in real time from its Console port (RJ45).
Every reading is on a web dashboard, opened over WiFi from your phone, tablet or PC at http://pylon-monitor.local, as well as through a JSON API and Home Assistant. Premium matte-black case with 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 when the Pylontech battery sits in a cellar, garage or plant room where nobody looks at a screen: every reading reaches your phone, PC or Home Assistant. The V3 build quality, for less than the screen model.
