Description
SKU: SR-RM-3
Mfg. SKU: RM-3
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

Why It’s Ideal for Canadian Off-Grid Solar
-
Remote Monitoring: Check system health from indoors—no roof climbs in Alberta winters or B.C. storms
-
Prevent Downtime: Instant fault alerts help you address battery or controller issues before they escalate
-
Optimize Battery Life: Accurate amp-hour tracking and temperature-compensated data extend battery lifespan in cold climates
-
Boost ROI: Maintain peak system efficiency and maximize energy yield for cabins, cottages and remote sites
