The SRNE HESP48120S200-H is a 48V, 12,000W hybrid solar inverter — the largest single-phase unit in SRNE’s HESP series. It’s built for households and commercial sites running heavy continuous loads, with two independent MPPT solar charge controllers and IP65 weatherproofing that lets it mount outdoors.
That outdoor rating sets the SRNE HESP48120S200-H apart from SRNE’s HYP and ASP series, which require indoor installation. It also carries a 5-year warranty, longer than the 2-year cover on SRNE’s smaller hybrid models.
What it does
Each SRNE HESP48120S200-H accepts up to 13,200W of solar input, split across two MPPT trackers rated at 6,600W each. As with SRNE’s other dual-MPPT units, this suits roofs or ground-mount arrays split across two orientations, with each string tracked independently.
Charging draws up to 200A from solar, 120A from grid, and 60A from a generator, with up to 200A combined when hybrid charging runs both sources at once. On a 12kW system that’s carrying real household or commercial load, that charging headroom matters — it’s the difference between a battery bank that recovers within a few hours of sun and one that takes most of the day.

Built for outdoor installation
Most SRNE hybrid inverters carry an IP20 rating and require a dry, indoor space. The SRNE HESP48120S200-H is different — its IP65 protection rating means it can mount outside, close to the battery bank and solar array, without a dedicated equipment room.
That matters for Kenyan sites where indoor space is limited or expensive to build out: a commercial rooftop installation, a farm outbuilding, or a residential compound where running long DC cable runs to an indoor cupboard isn’t practical.
Scaling power with parallel installation
One SRNE HESP48120S200-H covers 12kW of continuous load. Paralleling multiple units extends that further:
- Up to 6 units, in single-phase or three-phase configuration
- Automatic three-phase output once more than three units run together
- Time-slot charging control, letting the system draw from mains during off-peak tariff hours and switch to solar or battery during peak-rate periods
This suits larger Kenyan commercial and light-industrial sites — office parks, agri-processing plants, or manufacturing facilities — where load requirements exceed a single 12kW inverter.
Deployment scenarios in Kenya
Large households and estates A single SRNE HESP48120S200-H with a substantial 48V battery bank covers full household load — air conditioning, water heating, borehole pumps, and general circuits — through extended KPLC outages, with 6HP motor starting capacity for high-draw equipment.
Commercial and light-industrial sites Paralleling multiple units builds capacity for offices, processing facilities, or manufacturing sites in Nairobi, Mombasa, or Nakuru, where load grows in stages and outdoor mounting simplifies installation on sites with limited indoor equipment space.
Sites with limited indoor installation space The IP65 rating lets installers mount the SRNE HESP48120S200-H outdoors near the battery bank and PV array, cutting DC cable runs on sites where building an indoor equipment room isn’t practical or affordable.
Frequently asked questions
How is the SRNE HESP48120S200-H different from the SRNE ASP48100S200-H? The HESP48120S200-H is rated at 12,000W with an IP65 outdoor rating and a 5-year warranty. The ASP48100S200-H is rated at 10,000W, requires indoor installation (IP20), and carries a 2-year warranty. Choose the HESP48120S200-H for larger loads or outdoor mounting.
Can the SRNE HESP48120S200-H be installed outdoors? Yes. It carries an IP65 protection rating, unlike most SRNE hybrid inverters, which require indoor installation.
How many SRNE HESP48120S200-H units can run in parallel? Up to six units, in either single-phase or three-phase configuration.
What battery types work with the SRNE HESP48120S200-H? Lead-acid, lithium-ion, or user-defined profiles, rated at 48VDC with an operating range of 40VDC to 60VDC.
What is the maximum solar array size for one SRNE HESP48120S200-H? 13,200W total across two MPPT trackers, 6,600W per tracker, with each tracker rated up to 500VDC open circuit voltage.
