Diagram of off-grid System
In the mountainous and hilltop area of Kulambogan, Sibagat ADS, the Philippines, frequent power interruptions from the grid is common and normal to the residents there. To provide a more reliable study environment for the children, this school commissioned JMJ SOLAR to install two solar systems on top of this two-unit school building with two Growatt off-grid inverters, which is of 20kW power output in total. With the sustainable and stable power supply from the solar system, the school can then provide better conditions for the teachers and students.
Cerroasperosolar installed this off-grid solar storage system on an island where grid supply is beyond reach. An SPF ES off-grid inverter and two HOPE batteries, both offered by Growatt, were applied in this project, which will generate a green power supply and coexist harmoniously with the beauty of the island.
Thinking about going self-supply? In Pinamar, Argentina, BZ Energia Sustentable installed an off-grid solar energy storage system for this family who thought the same. With the solar modules installed on the rooftop, the Growatt SPF 5000 ES inverter allows the customer to use electricity generated by themselves. Moreover, the system equipped with HOPE Lithium Batteries can back up electrical power, bringing them reliable solar power when needed.
In this beautiful neighborhood in Parc Regency in the Philippines, SkyBright Solar has installed an off-grid solar energy storage system for one client. Four modules of Growatt’s ARK lithium-ion batteries were stacked and configured with an off-grid inverter SPF 5000 ES by the team, enabling the family to use solar power generated during the day for the night.
