The SRNE HFP4850S80-H is a 48V, 5,000W off-grid solar inverter. It runs on a single 80A MPPT solar charge controller and can be paralleled from one unit up to six.
Smaller SRNE 24V models suit a single room or small office. The SRNE HFP4850S80-H is built for bigger loads: larger households, multi-room offices, and commercial sites that need 5kW or more of continuous backup power from one system.
What it does
Each SRNE HFP4850S80-H accepts up to 5,500W of solar array input through its single MPPT channel. It charges from the grid or a generator at up to 60A, and can pull from solar and mains at the same time — up to 80A combined — when hybrid charging is switched on.
That combination matters when KPLC outages run long. A depleted 48V battery bank recharges faster, and the system keeps running even when solar alone can’t keep up.

Scaling power with parallel installation
One SRNE HFP4850S80-H covers 5kW of continuous load. But the unit is built to run in parallel banks of up to six.
What this makes possible:
- 10kW, 15kW, or larger single-phase systems by adding units as load grows
- A configured three-phase supply for sites running motors, pumps, or mixed single- and three-phase equipment
- Staged investment — a business installs one SRNE HFP4850S80-H now and adds units later, instead of replacing the whole inverter when capacity runs short
This suits Kenyan commercial and light-industrial sites, where power needs rarely stay fixed for long.
Built-in protection
The SRNE HFP4850S80-H protects itself and connected equipment on several fronts:
- Overcurrent protection (software and hardware) on battery discharge and solar charging circuits
- Overvoltage protection on the internal battery boost circuit
- AC output short-circuit and overload protection
- Over-temperature protection on both the solar charging and inverter radiators
For monitoring, it communicates over RS485, CAN, USB, or dry contact, with optional Wi-Fi or GPRS modules. Installers managing multiple sites across Nairobi, Mombasa, or Kisumu can check system status remotely instead of driving out for every fault.
Deployment scenarios in Kenya
Larger Nairobi and Nakuru households A single SRNE HFP4850S80-H with a 48V lithium battery bank covers lighting, refrigeration, water pumping, and home office equipment through extended KPLC outages. The 4HP motor starting capacity handles borehole or pressure pumps.
Multi-unit commercial and light-industrial sites Paralleling two or more SRNE HFP4850S80-H units builds capacity for offices, small factories, or agri-processing sites in Nakuru or Eldoret — useful where load grows in stages and a single 5kW inverter would fall short.
Off-grid rural installations With a 5,500W solar array feeding the single MPPT input, the SRNE HFP4850S80-H covers larger rural homes and farms beyond the KPLC grid. The 60A grid/generator charging current serves as backup during extended low-sunlight periods.
Frequently asked questions
How many SRNE HFP4850S80-H units can run in parallel? Up to six. That allows single-phase systems above 5kW, or a configured three-phase supply for mixed-load commercial sites.
What battery types work with the SRNE HFP4850S80-H? Lead-acid, lithium-ion, or user-defined profiles, rated at 48V with an operating range of 40VDC to 60VDC.
What is the maximum solar array size for one SRNE HFP4850S80-H? Up to 5,500W of PV array power through the single MPPT channel, at up to 500VDC open circuit voltage. Working MPPT range is 120VDC to 450VDC.
Can the SRNE HFP4850S80-H be installed outdoors? No. It’s rated IP20 and designed for indoor installation only, in a dry, well-ventilated space with fan cooling.
