SJ065J Protection - Custom Over/Under Voltage and Current Protector set for 5KW Solar Inverter.

Protect your solar investment with the SJ065J Digital Protection Module. Designed specifically for the high-demand requirements of 5kW inverters, this unit monitors the AC supply in real-time. If the municipal grid voltage spikes too high or drops too low (common during loadshedding transitions), the unit instantaneously disconnects the load to prevent inverter damage. It also features a customisable current limit, ensuring your system never exceeds its safe operating parameters. Once the grid stabilises, the unit automatically reconnects after a safe, pre-set delay.
Key Features:
Full Adjustable Protection: Customise your trip points for Over-voltage, Under-voltage, and Over-current.
Digital Dual Display: Real-time visual readout of both current Voltage (V) and Current (A).
Automatic Recovery: Intelligent timer ensures power only returns once the grid is stable for a set period.
Din Rail Mount: Fits standard DB boards for a clean, professional installation.
Ideal For:
Protecting 5kW Hybrid Inverters (Sunsynk, Deye, Luxpower, etc.).
Main DB board protection for homes in areas with unstable power.
Safe-guarding heavy appliances like borehole pumps and aircon units.
