Loadshedder 4 All-In-One Load Shedding Backup System overview

The Loadshedder 4 is purpose-built as a load-shedding and backup power system, not a full hybrid inverter. It combines an inverter, lithium-ion battery, battery management system and solar charge controller into a single all-in-one unit designed to supply essential loads only during grid outages.

This system is ideal for homes and small offices looking for reliable backup power without the complexity of a full solar hybrid installation.

Designed specifically for load-shedding protection

The Loadshedder 4 is intended to power critical circuits, such as:

• Lighting circuits

• Plug points for TVs and computers

• Wi-Fi routers and networking equipment

• Security systems and access control

• Small appliances and office equipment

It is not designed to operate high-demand appliances such as electric stoves, geysers, air conditioners or large motors.

Integrated inverter and lithium battery

This system includes a 3.6 kW single-phase inverter combined with a built-in lithium-ion battery. The integrated battery storage allows the system to supply power instantly during grid outages, while intelligent battery management protects against over-charging, deep discharge and overheating.

The all-in-one design reduces wiring, saves space and simplifies installation.

Solar input support for extended runtime

The Loadshedder 4 supports solar PV input, allowing solar panels to recharge the internal battery during the day. This extends backup runtime and reduces dependence on grid recharging, especially during extended load-shedding periods.

Dual MPPT inputs allow flexible solar panel configuration within the system’s design limits.

Fast automatic transfer and clean power output

With a 10 ms transfer time, the system switches automatically from grid power to battery power during outages, keeping essential electronics running without interruption. The inverter produces pure sine wave output, making it safe for sensitive electronic devices.

Safety, protection and reliability

Built-in protection features include overload, short-circuit and temperature protection. These safeguards ensure reliable operation and long-term system stability under typical residential and office backup conditions.
