Deye 20kW 48V Three-Phase Hybrid Solar Inverter in Kenya

The Deye 20kW 48V Three-Phase Hybrid Solar Inverter in Kenya is a high-capacity energy management solution designed for large homes, businesses, farms, schools, hotels, workshops and commercial properties that require three-phase solar power, battery storage and dependable backup.

The Deye SUN-20K-SG05LP3-EU-SM2 delivers 20,000W rated three-phase output while operating with a 40–60V low-voltage battery system. Unlike many commercial three-phase inverters that require high-voltage batteries, this model allows large solar installations to use compatible 48V / 51.2V lithium battery banks, giving system designers greater flexibility when building expandable energy-storage systems.

Built for High-Power Three-Phase Solar Systems

The Deye 20kW inverter is designed for properties with substantial electrical demand. It supports 220/380V or 230/400V three-phase systems and delivers up to 22kVA maximum apparent power.

Its off-grid output can provide up to 2 times rated power for 10 seconds, giving the system strong short-duration capacity for demanding equipment and motor-starting loads.

Typical applications include:

• Large residential homes
• Hotels and lodges
• Offices and commercial buildings
• Farms and agricultural facilities
• Schools and institutions
• Workshops
• Restaurants
• Retail premises
• Small industrial installations

Powerful Solar PV Capacity

The Deye SUN-20K-SG05LP3-EU-SM2 is designed to work with large solar arrays.

It supports up to 40kW maximum PV access power, while the manufacturer’s specified maximum PV input power is 32kW. This allows substantial PV oversizing to improve solar production during mornings, afternoons and periods of reduced irradiation.

The solar input provides:

• 800V maximum PV input voltage
• 160V start-up voltage
• 160–650V MPPT operating range
• 440–650V full-load MPPT range
• 550V rated PV voltage
• 2 independent MPPT trackers
• 2 PV strings per MPPT
• 36A + 36A maximum operating PV current

This makes the inverter suitable for modern high-power solar modules and large rooftop or ground-mounted PV arrays.

48V Battery Storage with up to 350A Current

A key advantage of the Deye 20kW 48V Hybrid Inverter is its low-voltage battery architecture.

The inverter supports batteries operating between 40V and 60V DC and can work with compatible lithium-ion or lead-acid batteries.

For the 20kW model, Deye specifies up to 350A maximum battery charging and discharging current and provides two battery inputs. Lithium battery charging can automatically adapt through compatible BMS communication.

This makes the inverter ideal for larger battery banks where longer backup time and higher discharge capability are required.

100% Unbalanced Three-Phase Output

Commercial properties rarely use exactly the same amount of electricity on every phase.

The Deye inverter supports 100% unbalanced output, allowing different loads to operate across the three phases without requiring perfectly balanced consumption.

Deye specifies maximum output of up to 50% of rated inverter power on an individual phase, providing useful flexibility for properties with uneven three-phase loads.

Generator and AC-Coupling Support

The inverter supports diesel generator energy storage, making it suitable for sites where a generator provides additional backup when solar and battery energy are insufficient.

It also supports AC coupling, allowing the Deye hybrid inverter to be integrated into appropriately designed existing solar installations.

This gives system designers flexibility to combine:

Solar + Battery + Grid + Generator

within one intelligent energy-storage system.

Smart Battery Scheduling

The Deye hybrid platform provides six programmable battery charging and discharging periods.

This allows battery operation to be scheduled according to electricity demand, available solar generation, backup requirements or time-of-use energy strategies.

For businesses, this can help preserve stored energy for periods when it is most valuable.
