Voltas HYD 20K-H6

The Voltas HYD-20K-H6 is a 20kW three-phase hybrid solar inverter in Pakistan, designed for commercial buildings, factories, offices and large solar systems that need three-phase output with battery storage. It manages solar power, battery storage and grid power in one unit, and its back-up output switches over in less than 10ms, so essential loads keep running during load shedding.

The inverter delivers a nominal AC output of 20kW (22kVA maximum) at 400V three-phase (3L+N+PE) and a back-up output of 20kVA (22kVA maximum). It accepts up to 40kW of DC input power with a maximum input voltage of 1000V and an MPPT working voltage range of 180V to 850V. It supports Li-ion and lead-acid batteries (40V to 60V) with a maximum charge / discharge current of 400A.

Choosing compatible solar panels, batteries and inverter equipment is essential for reliable system performance. Browse our solar inverters for other capacities, or the official Maxpower Voltas hybrid inverters catalog.

Key Features of the Voltas HYD-20K-H6 Inverter:

Three-Phase Hybrid Output
20kW nominal output at 400V (3L+N+PE) with a 22kVA maximum, suitable for three-phase commercial and industrial wiring and motor loads.

Wide MPPT Voltage Range
An MPPT working voltage range of 180V to 850V, a maximum DC input voltage of 1000V (600V nominal) and a 200V start-up voltage give flexibility in designing large solar arrays. The inverter has 2 independent MPPT trackers with 2 strings each and a maximum MPPT current of 2 x 36A.

Li-ion and Lead-Acid Battery Support
Works with Li-ion and lead-acid batteries within a 40V to 60V range. Li-ion charging self-adapts to the BMS, and lead-acid batteries use three-stage charging. This is a low-voltage battery inverter, so it is not designed for high-voltage (HV) battery stacks. Explore our lithium batteries to compare suitable energy storage options.

High Charging Capacity
A maximum charge / discharge current of 400A supports large battery banks for commercial back-up.

Efficient and Weather-Resistant
98% maximum efficiency, 97.5% European efficiency and a 94.4% maximum battery-to-load efficiency. The IP66 enclosure, smart cooling and -25°C to +60°C operating range suit outdoor installation. Monitoring is available through the LED display and WiFi / 4G / USB / CAN / RS485 communication.
