Inverter Remote Control with LCD & Bluetooth — Bypass Mode & Smart Charging
The RS-RM03 is the most capable remote in Rich Solar's NOVA SWITCH and NOVA SUPERCHARGER accessory lineup — combining wall-mounted LCD monitoring with Bluetooth control through the Rich Solar App. Beyond remote ON/OFF and mode switching, the RM03 adds bypass mode to keep critical loads powered through inverter faults, smart charging profiles tuned for AGM, lithium, and user-defined battery types, and flexible support for solar PV, grid, and battery inputs across off-grid, hybrid, and grid-tied configurations.
Bluetooth Control Through the Rich Solar App
Beyond the wall-mounted panel, built-in Bluetooth connects to the Rich Solar App for remote mode switching and performance tuning from a smartphone — manage your inverter without standing at the panel or walking to the unit itself.
Bypass Mode Keeps Critical Loads Powered
If the inverter faults, bypass mode automatically maintains power to critical appliances rather than dropping the load entirely — a meaningful reliability feature for medical equipment, refrigeration, communication gear, or anything that can't tolerate an unplanned outage.
Smart Charging for AGM, Lithium & Custom Profiles
Optimized charging profiles for AGM and lithium chemistries, plus user-defined custom profiles for less common battery types — improving charging efficiency and helping extend overall battery service life compared to a one-size-fits-all charging curve.
Product Overview
The Rich Solar RS-RM03 is a wall-mounted remote control and monitoring panel for the NOVA SWITCH and NOVA SUPERCHARGER inverter series — the premium tier in Rich Solar's NOVA remote accessory lineup. It shares the same RJ12 plug-and-play connection, flush wall-mount form factor, and HD backlit LCD as the standard RM02 remote, but adds Bluetooth connectivity, bypass mode, smart charging profiles, and multi-source energy input support that the standard remote doesn't offer.
The LCD displays real-time power, voltage, load, and battery status at a glance, with advanced fault alerting through dual-color LED indicators, an audible buzzer, and on-screen fault codes — the same three-layer alert system used across the NOVA remote family. Where the RM03 goes further is Bluetooth: pairing with the Rich Solar App allows mode switching and performance tuning from a smartphone, useful when you're away from the wall panel but still want visibility or control over the inverter's operation.
Bypass mode is the standout reliability feature. If the inverter encounters a fault condition, bypass mode keeps power flowing to connected loads instead of cutting off entirely — important for anyone running equipment that can't tolerate an unplanned interruption. Combined with smart charging profiles tuned specifically for AGM and lithium batteries (plus the ability to define custom profiles for other chemistries), and support for solar PV, grid, and battery inputs across off-grid, hybrid, and grid-tied system configurations, the RM03 is built for installations where flexibility and uptime matter more than a basic on/off remote.
Control From Your Phone, Not Just the Wall
- Built-In Bluetooth: Connects directly to the Rich Solar App on your smartphone — no separate Bluetooth dongle or additional hardware required.
- Remote Mode Switching: Change the inverter's operating mode from the app without walking to the wall panel — useful when you're elsewhere in an RV, on a boat deck, or outside a cabin.
- Performance Tuning: Adjust inverter settings and parameters through the app interface, which can offer more detailed configuration options than the wall panel's physical interface alone.
- Dual Control Paths: Use the flush-mounted wall panel for quick on/off and at-a-glance monitoring, or the app for deeper configuration and remote access — choose whichever fits the moment.
- No Wireless Range Anxiety for Core Functions: The wall panel itself remains wired via RJ12 for reliable core control and monitoring — Bluetooth adds a layer of convenience without making essential functions dependent on a wireless connection.
Bypass Mode — Power That Doesn't Just Stop
- Automatic Fault Bypass: If the inverter encounters a fault, bypass mode keeps power flowing to connected loads rather than dropping power entirely — a meaningful step up from a standard inverter shutdown.
- Critical Load Protection: Particularly valuable for equipment that can't tolerate an unplanned outage — medical devices, refrigeration, communications equipment, security systems, or sump pumps in a cabin or off-grid home.
- Reduces Downtime Risk: Rather than troubleshooting a faulted inverter while the power is completely out, bypass mode buys time to diagnose and resolve the issue without an interruption to connected loads.
- Works Alongside Fault Alerting: The same LED, buzzer, and fault code system that flags the issue also coincides with bypass mode engaging — you're alerted to the problem while critical loads stay powered.
- Particularly Relevant for Off-Grid & Hybrid Systems: Where backup power options may be limited, bypass mode adds a layer of resilience that standard remotes don't provide.
Smart Charging That Matches Your Battery
- AGM Charging Profile: Optimized voltage and current curves tuned specifically for AGM lead-acid batteries — improving charge efficiency over a generic charging algorithm.
- Lithium Charging Profile: A dedicated profile suited to LiFePO4 and other lithium chemistries commonly used in modern RV, marine, and off-grid battery banks.
- User-Defined Custom Profiles: For battery types outside the standard presets, set your own charging parameters — useful for less common chemistries or manufacturer-specific charging recommendations.
- Solar PV, Grid & Battery Input Support: The system adapts to whichever power source is available — solar panels, utility grid, or battery — suitable for off-grid, hybrid, and grid-tied installations rather than a single fixed configuration.
- Seamless Source Switching: Automatically adapts between available power sources to maintain stable, uninterrupted operation as conditions change throughout the day.
Rugged Build, Simple Wall Installation
- Flame-Retardant ABS Housing: Resists vibration and shock — appropriate for mobile installations in RVs, vans, and marine environments subject to ongoing mechanical stress.
- HD Backlit LCD: Clear readability of power, voltage, load, and battery status in low-light environments including nighttime use and dimly lit equipment rooms.
- Three-Layer Fault Alerts: Dual-color LED indicators, an audible buzzer, and on-screen fault codes provide redundant notification of any issue, regardless of whether you're watching the display.
- Flush Wall-Mount, RJ12 Plug-and-Play: 5.4 × 3.4 × 1.3 in panel with a 4.3 × 2.3 in cutout and 1.97 in recess depth — fits standard panel cutouts with a fast, tool-minimal RJ12 connection.
- Consistent NOVA Remote Family Form Factor: Mounting dimensions are close to the standard RM02 remote, simplifying installation for anyone already familiar with mounting Rich Solar's NOVA remote accessories.
