The SRNE HF2430U80-H 3kW Single Phase Hybrid Inverter/Charger is a hybrid solar inverter charger that combines a 3,000W pure sine wave inverter, a multi-source MPPT battery charger, and an AC bypass in a single wall-mount unit. It accepts up to 4,000W of string PV input, charges a 24V battery bank from solar, grid, or generator, and delivers 120Vac single-phase power to connected loads — prioritizing solar energy to minimize grid or generator draw.
Note: This inverter does not export solar power to the utility grid. It includes AC back-filling protection that blocks reverse power flow to the grid, using AC input for battery charging only. Buyers planning to export solar power back to the utility will need a grid-tied inverter instead.
Note: The HF2430U80-H is designed exclusively for 24V battery banks (20–33Vdc operating range). It is not compatible with 48V or 12V battery systems.

Three charging sources, one unit
Off-grid solar systems traditionally require separate components for solar charging, AC backup charging, and load inversion — creating complex wiring and additional failure points. The HF2430U80-H consolidates all three into a single indoor wall-mount enclosure: solar is the priority charging source, grid or generator steps in as backup, and the 10ms transfer time keeps most loads running through a source switch. Programmable charge and load modes let the installer control how the system balances solar priority, battery longevity, and AC input draw.
Key Applications
- Off-grid cabin or homestead: Provides a complete solar inverter and charging solution for properties without utility grid access, using solar as the primary source with generator as backup for extended low-sun periods.
- Home backup with grid-charge: Installs in a home to deliver battery-backed 120Vac power to critical loads, drawing solar first and using the grid connection to top off the battery — without exporting power back to the utility.
- RV and mobile off-grid: Multi-source charging and single-phase 120Vac output make it a practical fit for RV setups where solar is primary and shore-power connection provides backup battery charging while parked.
- Small off-grid commercial: Powers essential loads at remote agricultural sites, equipment shelters, or small off-grid workshops where 3,000W of 120Vac output covers lighting, controls, and moderate motor loads.
- Generator-solar hybrid systems: Pairs with a fuel generator for reliable backup charging while solar handles daily energy production, reducing generator run time and fuel costs.
Monitoring and protection suite
- Remote monitoring: Built-in RS485/CAN/USB and dry contact ports enable BMS integration and system monitoring; an optional Wi-Fi/GPRS module supports remote access and parameter logging.
- Comprehensive protection: Includes PV anti-reverse, over/under-voltage on battery and AC input, output short-circuit, overload, radiator over-temperature, and AC back-filling protection — covering the full range of common fault conditions.
- Fan cooling: Active fan-cooling system manages heat dissipation under sustained load, supporting reliable operation across the full 5°F–131°F (−15°C–55°C) operating temperature range.
PV, battery, and AC wiring
PV panels must be wired as a single string to the one MPPT input — max open-circuit voltage is 500Vdc, MPPT range is 120–450Vdc, and max input current is 13A; size your string accordingly. Battery bank must be 24V nominal; supported types include sealed lead-acid, flooded lead-acid, lithium-ion, and user-defined profiles. Grid or generator AC input accepts 90–140Vac at 50/60Hz, with a 40A bypass overload current rating. The unit supports 2HP motor loads. Dimensions: 14.88 × 11.02 × 4.06 in. (378 × 280 × 103 mm); weight: 17.64 lbs. (8 kg).
Why choose the SRNE HF2430U80-H?
For buyers building a 120Vac off-grid or battery-backup solar system around a 24V battery bank, the SRNE HF2430U80-H eliminates the complexity and cost of sourcing a separate inverter, solar charge controller, and AC transfer switch. Its three-source charging capability, 99.9% MPPT tracking efficiency, and cETL UL1741 certification make it a well-specified and US-market-compliant choice for residential off-grid and home backup installations. Available through A1 SolarStore with a 2-year manufacturer warranty, it is backed by SRNE's 15-year track record in PV product development.
