SRNE RM-3 Remote LCD Meter
Overview
Indoor touch-screen LCD display for real-time monitoring of off-grid solar charge controllers in Canada
Automatically cycles through PV voltage, battery status, charge/discharge currents and error codes every 10 seconds
Plugs directly into SRNE controllers via a standard 6-pin RJ12 cable—no external power source required
Key Features
Multi-Parameter Monitoring: View PV array voltage, battery voltage, charging current, load current, amp-hour tally and controller temperature in one place
Touch & Auto-Browse Modes: Short tap to scroll manually; long press to enter auto-browse (5 sec per parameter) or reset historical Ah data
Built-In Fault Alerts: Error codes and visual icons alert you to overcharge, discharge, overload or communication issues
Rugged Design: Industrial-grade electronics rated for –35 °C to +65 °C, ideal for Canadian cottages, cabins and remote installations
LED Status Indicators
Charging Lamp:
Off = no solar input
On = bulk charge
Fast blink = equalization
Slow blink = boost
Single blink = float
Double blink = current limit
Battery Lamp:
Off = no battery
On = normal
Fast blink = overvoltage
Slow blink = discharge
Load Lamp:
On = load active
Off = load off
Fast blink = overload/short-circuit
Slow blink = communication error
