The Voltas 14K-H4 is a 14kW three-phase hybrid solar inverter in Pakistan, engineered to optimize solar energy usage and provide reliable power for industrial and commercial applications as well as large homes with three-phase supply. This hybrid solar inverter combines solar input, battery storage and UPS back-up output in one unit, so it works with the grid and keeps essential loads running during load shedding. It is a dependable choice for users seeking an efficient energy source.

Key Features:

• Battery Input: Compatible with lead-acid or Li-ion batteries, with a 40V to 60V battery voltage range. This is a low-voltage battery inverter, so it is not designed for high-voltage (HV) battery stacks.
• Max. Charge and Discharge Current: 280A for both, ensuring efficient energy management.
• Charging Strategy: A 3-stage charging curve with equalization, self-adaption to the BMS for Li-ion batteries (CAN / RS485), and an optional external temperature sensor for enhanced performance.
• Three-Phase Output: 14,000W rated AC output and UPS power (15,400W maximum) at 380/400Vac, with a peak power of 1.8 times the rated power for 10 seconds off-grid.

With a maximum DC input power of 20,000W, a PV input voltage of 650V (160V to 800V), an MPPT range of 200V to 700V and 2 MPPT trackers (2 + 1 strings), the inverter handles large solar arrays, with a start-up voltage of 160V. It reaches a maximum efficiency of 97.90% and a 99.90% MPPT efficiency. Protection includes PV input lightning protection, anti-islanding, reverse polarity protection, insulation resistor detection, residual current monitoring, output over-current and short-circuit protection and DC Type II / AC Type III surge protection, with PV ARC fault detection available as an option. With an IP65 rating, smart cooling, wall-mounted installation (45kg) and a 5-year warranty, the Voltas 14K-H4 delivers reliable performance in various environments.
