Off-Grid Inverter SRNE Single-Phase 3.3 kW 24V – HF2430S80-H

SRNE HF2430S80-H 3300W 24V Off-Grid Solar Inverter – The 3-in-1 solution for energy self-sufficiency

The SRNE HF2430S80-H is a 3,300W single-phase 24V off-grid solar inverter that combines three essential functions for any off-grid installation into a single compact unit: a pure sine wave inverter, an MPPT solar charge controller and a battery charger. This 3-in-1 integration simplifies wiring, reduces the footprint and lowers the overall cost of the installation compared to using three separate devices. It is aimed both at private individuals wishing to become off-grid and at professionals equipping remote sites, technical containers or off-grid construction sites.

Pure sine wave inverter: grid-quality power

The SRNE HF2430S80-H produces a pure sine wave at 230V output, identical to that of the public mains supply. This waveform is essential for correctly powering sensitive equipment: electric motors, pumps, fridges, freezers, audiovisual equipment, computers, and any device with a switching power supply or variable speed drive. Unlike quasi-sinusoidal (modified) waveform inverters, the HF2430S80-H does not generate electromagnetic interference that could damage connected devices or cause noise in audio equipment.

Integrated MPPT controller: maximising every solar watt

The integrated MPPT solar charge controller continuously optimises the maximum power point of the connected panels, regardless of light levels or temperature. Compared to a conventional PWM controller, MPPT technology allows up to 30% more energy to be recovered in difficult conditions (overcast skies, low temperatures, long cabling). This direct integration into the inverter eliminates the need to install a separate charge controller, simplifying the system architecture and reducing losses associated with intermediate connections.

Integrated battery charger: multi-source and flexible

The HF2430S80-H features a built-in battery charger that allows the battery bank to be recharged from the mains grid or a generator via its AC input (170–280 Vac). This function is particularly useful during prolonged periods of low sunlight or in winter, when solar generation is insufficient to keep the batteries charged. The charger ensures appropriate charging according to the configured battery type, adhering to the correct charging profiles to preserve battery life.

Battery compatibility: 24V lithium and lead-acid

The SRNE HF2430S80-H is compatible with all 24V battery technologies available:

• LiFePO4 lithium: long service life (2,000–6,000 cycles), lightweight, deep discharge possible up to 80–90%
• Lithium NMC: high energy density, compatible with lithium batteries featuring BMS communication
• AGM (Absorbent Glass Mat): maintenance-free, vibration-resistant, ideal for mobile or hard-to-reach installations
• GEL: excellent tolerance to deep discharge, long cycle life, suitable for fixed installations
• OPzS: tubular batteries with liquid electrolyte, very long service life (15–20 years), ideal for large fixed storage capacities

The battery type is configured directly on the inverter to adapt the charging profiles (charging voltage, cut-off voltage, charging current) to the technology used.

Intelligent multi-source management

The HF2430S80-H automatically manages the priority between the three available energy sources: solar panels, batteries andthe mains/generator input. In normal operation, the solar system powers the loads and charges the batteries simultaneously. When the batteries reach a configurable discharge threshold, the inverter can automatically switch to the AC input (grid or generator) to recharge the batteries and maintain power to the loads without interruption. This automatic management ensures maximum power continuity even during periods of low solar production.

Recommended applications

Off-grid homes and permanent off-grid living

The SRNE HF2430S80-H powers the essential appliances in a home: LED lighting, fridge, freezer, television, internet router, computers, smartphone chargers and small household appliances (coffee machine, low-power microwave). With 3,300 W of continuous power, it covers the majority of the needs of an energy-efficient household. For appliances with high inrush current on start-up (motors, compressors), you should check that the appliance’s starting power remains within the limits permitted by the inverter.

Chalets, mountain huts and remote holiday homes

Ideal for mountain chalets, mountain huts or second homes far from any mains connection, the HF2430S80-H provides reliable and silent electricity. Its compact size (7.4 kg) makes it easy to transport and install in confined spaces. As there is no need to connect to the public grid, connection costs—which can be very high in rural or mountainous areas—are eliminated.

Farms and rural sites

On farms equipped with solar panels, the HF2430S80-H can power standard electrical equipment: building lighting, low-power pumps, surveillance systems and power tools. Compatibility with a backup generator ensures uninterrupted power supply during winter months or in the event of a failure.

Uninterruptible backup power

In backup mode, the HF2430S80-H maintains power to priority loads during a prolonged mains power cut. Connected to a sufficient battery bank and solar panels, it provides autonomy ranging from several hours to several days, depending on the installed storage capacity and the site’s consumption.

Mobile professional sites and construction sites

Mobile offices, technical containers, off-grid construction sites, temporary pumping stations: the compact size and low weight of the HF2430S80-H (7.4 kg) make it easy to move and quick to set up at temporary or mobile sites.

Built-in protection and reliability

The SRNE HF2430S80-H incorporates all the protection features necessary for reliable and long-lasting use:

• Overload protection: automatic shutdown if power consumption exceeds the permissible limit
• Short-circuit protection: immediate shutdown in the event of an output short-circuit to protect the inverter and connected devices
• Battery overvoltage protection: charging stops if the battery voltage exceeds the maximum permissible threshold
• Battery undervoltage protection: automatic cut-off before excessive discharge to preserve battery life
• Overheating protection: derating or automatic shutdown in the event of excessive internal temperature
• Reverse polarity protection: protection against battery wiring errors
