Hinen’s H15000T series hybrid inverter supports unbalanced 3-phase distributed grid
It is designed for up to 150% DC/AC oversizing
During grid failure or outages, the system offers continuous backup for a certain duration, while it lasts for up to 10 seconds under surge voltages
With the European and African high-capacity residential (3-phase) and small commercial solar-plus-storage market in focus, Hinen New Energy, a provider of energy storage solutions (ESS), has launched the H15000T series 3-phase hybrid inverter.
This inverter, consisting of 3 independent MPPT channels, supports PV strings placed at a varied shadow-free roof orientation without any current (DC) mismatch. The company says that these channels are designed to support up to 150% additional DC capacity (22.5 kW) with respect to the inverter’s rated AC capacity (15 kW) and have a starting voltage of 150V to maximize solar harvesting even in low light conditions. It can deliver the rated output current, which is unevenly distributed among 3-phases, feeding residential and commercial unbalanced loads.
On the energy storage side, its DC inputs support up to 290 A charging/discharging (cycle) of the connected battery banks; however, the company didn’t specify the maximum rated storage capacity (kWh) of the inverter. This stored energy supports up to 110% of the rated 3-phase power (AC) as backup (continuous overload) after switching to backup mode under 10 ms of grid failure or outages, maintaining uninterrupted operations. However, to address the surge current, typically generated by inductive loads during this transition phase, it is designed to support up to 200% overload (backup) for up to 10 seconds. This inverter can also be bypassed to directly connect with the grid and supply up to 45 A current with a maximum load of 30 kW, making it suitable for high load appliances, machinery, and commercial equipment.
