The SRNE HESP48200SH3 is a 48V, 20,000W three-phase hybrid solar inverter — the largest unit in SRNE’s HESP 16-20kW three-phase series. It’s built for industrial and large commercial sites running loads that exceed even the 16kW HESP48160SH3, with three independent MPPT solar charge controllers and IP65 weatherproofing for outdoor mounting.
Against the SRNE HESP48160SH3’s 16,000W output, the SRNE HESP48200SH3 steps up on every current rating that matters at this scale: more output power, higher charging current, and a larger total solar array capacity, while sharing the same physical footprint and installation approach.
What it does
Each SRNE HESP48200SH3 accepts up to 30,000W of solar input, split across three MPPT trackers rated at 26A each. As with the smaller HESP48160SH3, three independent tracking channels suit large commercial roofs or ground-mount arrays split across multiple orientations, with each string optimized independently.
Charging draws up to 350A from grid, generator, or combined hybrid sources — the highest charging current across SRNE’s HESP range. For an industrial site running continuous three-phase loads, that current recovers a large 48V battery bank quickly after a KPLC outage, minimizing the window where the site runs on stored charge alone.

Built for real-world three-phase loads
Like the rest of SRNE’s HESP three-phase series, the SRNE HESP48200SH3 supports 100% three-phase unbalanced output, with each phase capable of carrying over 50% of rated power independently. On an industrial site where three-phase motors and single-phase office or lighting circuits draw unevenly across phases, this prevents overload trips that a strictly balanced system would trigger.
AC coupling support lets installers pair the SRNE HESP48200SH3 with an existing grid-tied solar installation, adding battery backup without replacing the original inverter. Smart load management on the generator port handles secondary loads when no generator is connected.
Scaling power with parallel installation
One SRNE HESP48200SH3 covers 20kW of continuous three-phase load — already the largest single unit in SRNE’s HESP lineup. Paralleling extends that substantially further:
- Up to 9 units in parallel
- Up to 180kW achievable across a fully paralleled bank
- Time-slot charging control, favoring mains during off-peak tariff hours and switching to solar or battery during peak-rate periods
This suits the largest Kenyan commercial and industrial sites — manufacturing plants, large agri-processing facilities, and multi-building industrial parks — where load requirements exceed what a handful of smaller inverters would efficiently cover.
Deployment scenarios in Kenya
Manufacturing and heavy industrial sites A single SRNE HESP48200SH3, or several paralleled together, covers large three-phase motor loads, industrial processing equipment, and facility-wide power through extended KPLC outages, with 12HP motor starting capacity for large compressors, chillers, or pumps.
Large agri-processing facilities The 30,000W PV input capacity and 350A charging current suit sites with large rooftop or ground-mount solar arrays paired with sizable battery banks, common at processing plants in Nakuru, Eldoret, or the Rift Valley.
Multi-unit industrial parks Paralleling toward 180kW across multiple SRNE HESP48200SH3 units serves industrial parks or large commercial complexes where power demand grows across several buildings or production lines.
Frequently asked questions
How is the SRNE HESP48200SH3 different from the SRNE HESP48160SH3? The HESP48200SH3 delivers 20,000W with 350A maximum charging current and 30,000W total PV input capacity. The HESP48160SH3 delivers 16,000W with 300A charging current and 24,000W total PV input capacity. Both share the same three-MPPT design, IP65 rating, and 9-unit parallel capacity — choose the HESP48200SH3 for the largest single-unit capacity in the series.
How many SRNE HESP48200SH3 units can run in parallel? Up to nine units, matching the rest of SRNE’s HESP 16-20kW three-phase series.
What battery types work with the SRNE HESP48200SH3? Lithium-ion, lead-acid, or user-defined profiles, rated at 48VDC with an operating range of 40VDC to 60VDC.
