Emergency power supply POWER SINUS 3000 24/230V (3000/9000W) 3SSP300024

Pure sine wave output – powering devices with high inrush current

The device generates a sinusoidal voltage identical to the grid supply – a critical feature that enables safe operation of inductive loads. There are no artificial square waves or modified waveforms that can damage motors or electronics. Therefore, it operates stably with refrigerators, freezers, air compressors, central heating pumps, or ovens – where a standard UPS would shut down or overheat.

High inrush current and fast switching

It can deliver up to 9000 VA of transient power (for up to 20 seconds), sufficient to start motors with high inrush current – such as a refrigerator compressor or heat pump. The switching time between grid and battery is only 10 ms – short enough to avoid disrupting sensitive equipment. There’s no need to turn off the system during a power outage – the device responds almost imperceptibly.

Charger and inverter in one – ready for 24V batteries

You don’t need a separate charger or external converter. This is a complete system: it converts energy from the battery to 230V AC while simultaneously charging the battery from grid voltage in the range of 164–243V. It supports various 24V battery types – from conventional lead-acid to modern AGM or GEL. Charging current reaches up to 45A, and the desulfation function extends battery life.

Built-in protections – no user intervention required

The device automatically ensures safety: it detects overload, short circuits, excessive temperatures, and low battery voltage. When the battery approaches deep discharge, it automatically reduces load or shuts down. It also prevents overcharging – no manual battery monitoring is needed.

One solution for installer and end-user

For the installer, setup is simple: connect 24V batteries, plug in the grid and load – ready to go. No need to select separate components. For the end-user, it means peace of mind: even during prolonged grid outages, central heating pumps or refrigerators continue running without interruption. In photovoltaic systems, it functions as a hybrid inverter – capable of operating both with the grid and independently from the battery.
