Island Photovoltaic Energy Storage System
Independent solar power for remote island communities.
Solar panels generate electricity that is stored in batteries to support an independent island power supply. Industrial-frequency off-grid inverters and photovoltaic controllers form part of the system configuration.
Marine Lithium-ion Energy Storage System
Energy storage and power conversion for onboard electrical loads.
Marine electrical systems supply navigation, communication and onboard facilities. This project reference combines lithium-ion energy storage with inverter equipment designed around the voltage, frequency and isolation requirements of marine use.
Photovoltaic Pumping System
Solar-driven water supply for irrigation and remote locations.
A solar pumping system converts photovoltaic energy to drive a three-phase AC water pump. A complementary grid supply can support pumping when solar generation is insufficient, depending on the selected system configuration.
Photovoltaic Oil Pump System
Photovoltaic power conversion for oil pumping equipment.
This project reference uses photovoltaic modules and dedicated inverter equipment to support oil pump operation. Industrial-frequency isolation and load handling are relevant considerations when specifying equipment for remote or demanding sites.
Charging & Energy Storage System
Integrated power conversion for electric vehicle charging.
Combining battery storage with inverter and charging equipment supports power delivery to electric vehicle charging facilities. Renewable generation and stored energy can be coordinated to support the charging load.
