The SRNE 3kW Solar Off-Grid Inverter HF2430S60-108 integrates a 60A MPPT solar charge controller, battery inverter, and mains-charging function into a single 24V unit. It converts battery power into 230V pure sine wave AC output while managing solar charging directly, making it suited to medium-sized off-grid systems and homes needing a step up from a 12V entry-level inverter.
What Is the SRNE HF2430S60-108?
The SRNE 3kW Solar Off-Grid Inverter is a 24V all-in-one inverter/charger rated at 3,000W continuous output with a 6,000VA peak surge capacity. Where the 1.5kW/12V models suit lighter household loads, the 24V/3kW configuration is built for medium-sized off-grid systems, small businesses, or homes running multiple appliances simultaneously — a fridge, TV, water pump, and lighting circuit together, for example.

Why the 24V/3kW Configuration Fits Medium-Sized Systems
- 6,000VA peak surge handles the startup draw of motor-driven appliances like water pumps and fridge compressors, which a smaller inverter can struggle with
- 24V battery architecture allows a lower-current, thinner cable run between battery and inverter compared to 12V systems at the same power rating, reducing voltage drop over distance
- Four charging modes let installers set Solar Priority for daytime independence and switch to Mains Priority automatically when battery levels drop, useful where grid power is reliable but expensive
- Battery monitoring function gives real-time voltage, current, and temperature data, which helps installers diagnose battery bank issues remotely rather than guessing on-site
- Optional WiFi module supports app-based monitoring, letting a technician check system status across multiple client installations without a physical visit
Deployment Scenarios
For a medium-sized Nairobi or Nakuru household running a fridge, water pump, TV, and full lighting circuit through KPLC outages, the SRNE HF2430S60-108 paired with a 24V lithium or lead-acid battery bank and a matched solar array covers the load comfortably where a 1.5kW/12V unit would fall short on surge capacity alone.
For small businesses — a barbershop, cyber café, or retail shop running refrigeration, point-of-sale systems, and lighting — the 3kW rating and Mains Priority mode keep operations running through load-shedding windows without needing a generator as a first line of backup.
In off-grid rural settings across Kenya where there’s no grid connection at all, the Only Solar charging mode lets the SRNE 3kW Solar Off-Grid Inverter run entirely on a solar array and battery bank, independent of any mains input.
Kenya-Specific Considerations
The step up from 12V to 24V battery architecture matters for installers sizing systems beyond basic household lighting, since the HF2430S60-108’s higher voltage reduces cable losses on longer battery-to-inverter runs common in larger Kenyan homes and small commercial premises. As with other units in the HF series, it’s rated for indoor use only, so ventilation and dry conditions matter for installations in humid coastal regions or during Kenya’s rainy seasons. Buyers moving up from a 1.5kW/12V system should also confirm their existing battery bank is being upgraded to 24V rather than assumed compatible, since the two voltage classes aren’t interchangeable without rewiring the bank.
Frequently Asked Questions
Can the SRNE HF2430S60-108 run appliances with an electric motor, like a water pump?
Yes. The 6,000VA peak surge capacity is designed to handle the higher startup current that motor-driven appliances draw, which a lower peak-rated inverter may not sustain.
Is this the same as the 1.5kW/12V SRNE inverter?
No. This model runs on a 24V battery system with double the continuous output (3kW vs 1.5kW) and double the peak surge capacity, suited to heavier loads.
Does it need a WiFi connection to work?
No, the WiFi module is optional for remote monitoring. The inverter functions fully without it.
What battery types does it support?
Both lead-acid and lithium-ion 24V battery banks, with battery monitoring for voltage, current, and temperature.
