Monitoring Kits

Battery Monitor, Tank Level and System Monitoring Kits

A voltage reading alone does not tell you how much energy is left in your battery bank, how full your water tanks are, or what your solar array is producing. These monitoring kits bundle a display with the matching shunts, sensors and cables, so you can track battery state of charge, solar yield, tank levels and temperatures accurately. Each kit suits caravans, RVs, boats, 4WD canopies, tiny homes and off-grid installs.

Shunt Battery Monitor and Tank Kits from Simarine

The Simarine Pico display panel kits pair a panel-mount black display with a high-precision battery shunt. Together they work as a full shunt battery monitor that measures current in and out of your battery bank. Three configurations are available:

• Pico + 300A shunt: Includes 2x voltage, 2x resistive and 1x temperature inputs. Suits single-bank caravan and 4WD systems.
• Pico + 300A shunt + quad shunt/tank module: Adds extra current channels and tank inputs for multi-circuit monitoring.
• Pico + 500A shunt + quad shunt + quad tank module: Built for larger lithium banks, high-draw inverters and boats with several tanks.

Victron Cerbo GX Kits for Remote Monitoring

For Victron-based systems, the Cerbo GX MK2 combos pair the system controller with a GX Touch 50 or GX Touch 70 display. The Cerbo GX brings together data from connected Victron battery monitors, MPPT solar charge controllers, inverter/chargers and DC-DC chargers, and shows it on one touchscreen. With an internet connection, it also gives you remote solar monitoring through the Victron VRM portal.

The system bundles add a 5m display extension and temperature sensors, which make cabinet and battery-compartment installs easier. To expand thermal monitoring, add the 6mm slim temperature sensor 4-pack. It suits the Ekrano and Cerbo GX and fits tight battery terminals and enclosures. If you are still deciding on a controller, compare the Victron Cerbo, Ekrano, Color Control and Venus GX devices before you buy.

For simpler solar-only setups, the Victron MPPT Control LCD with 5m VE.Direct cable gives a dedicated remote readout for compatible VE.Direct MPPT controllers.

Votronic Tank Level Monitoring Systems

The Votronic Tank Level Sensor Electrode 15-50K kits include a Tank Display S. Versions are available for fresh water, grey water and black/toilet water. They are a straightforward tank level monitoring system for caravans, motorhomes and boats where knowing your water reserves matters as much as your battery capacity.

How to Choose the Right Monitoring Kit

Battery monitoring: Match the shunt rating to your peak continuous current. Choose a 300A shunt for typical caravan and 4WD loads, and step up to 500A for large inverters or marine house banks.

System integration: If your setup already uses Victron chargers and controllers, a Cerbo GX kit centralises data and adds remote access. A Simarine Pico suits mixed-brand systems that need battery and tank data on one panel.

Display size and mounting: The GX Touch 70 offers a larger screen for motorhome dashboards and helm stations. The GX Touch 50 and Pico suit compact cabinets and canopies.

Tanks and sensors: Count your water tanks and temperature points before you buy. Then choose a kit with enough inputs, or plan to add Votronic tank displays or extra temperature sensors.
