Essential accessories for your solar charge controller

Charge controller accessories ensure efficient and safe charging of the battery bank. With sensors, displays, communication modules, and appropriate DC protections, you can optimize voltages, monitor the system, and extend the service life of batteries in off-grid and self-consumption installations with storage.

What you will find in this collection

• Temperature sensors: adjust the charging voltage according to the bank’s temperature to prevent over/undercharging.
• Displays and remote screens: display voltage, current, daily energy, and states (absorption/float).
• Communication modules: Bluetooth/Wi-Fi/RS485/CAN for monitoring via app/portal and integration with other equipment.
• DC protections: fuses and fuse holders near the battery, disconnect switches, and SPD (surge protection devices).
• Wiring kits: jumpers, terminals, heat-shrink, and accessories for clean connections.
• Mounts and enclosures: organization of the DC panel and proper ventilation for the controller.

Quick compatibility guide

• Check the brand/series of your MPPT or PWM before choosing a display or communication module.
• Confirm the voltage/current range of fuses, disconnect switches, and SPD for your system (12/24/48 V and maximum A).
• For lithium batteries, check if the controller supports communication with BMS or specific profiles.

Installation best practices

• Install a fuse on the positive battery–controller line and an accessible disconnect switch for maintenance.
• Place an SPD on DC PV/battery if applicable and keep the voltage drop <3% on critical cables.
• Connect the battery to the controller first, then the PV array (according to the manufacturer’s manual).
• Use the temperature sensor and correctly configure absorption, float, and, if applicable, equalization.

Related accessories you may be interested in

• Battery monitors (shunt) to measure SOC, current, and consumption.
• Inverter accessories (meters/CT, communications) if controller and inverter are used together.
• Battery accessories for wiring and bank protection.

With the right accessories, your controller will operate under optimal conditions: higher performance, greater safety, and monitored operation that extends the system’s lifespan. Choose components compatible with your equipment and enjoy a clean, reliable installation.
