Technical FAQs 4

What is a hybrid solar inverter & lithium battery storage system?

Seamlessly combining a hybrid solar inverter and lithium battery storage, it provides a reliable, scalable, and cost-effective way to harness the power of the sun. With its modular design, this stackable energy storage system is perfect for scalable applications, providing a flexible, efficient, and reliable energy management solution.

How can on-site solar PV & energy storage improve sustainability?

To achieve sustainability goals while meeting the increasing electricity demands of electrification, organizations are pairing on-site solar PV generation with on-site energy storage. These systems, which are considered as “behind-the-meter” (BTM) systems, allow facilities to maximize the benefits of on-site renewable generation.

How does a solar energy storage system work?

Equipped with advanced monitoring and control features, this integrated energy storage system provides intelligent energy management that optimizes energy use based on real-time conditions. With reliable lithium batteries, it ensure that stored energy remains available during periods of low sunlight or grid outages.

Can on-site storage be used alongside solar PV?

If a utility restricts the exports from a facility to the grid, the use of on-site storage alongside solar PV can provide a solution to avoid costly infrastructure upgrades, thus increasing the feasibility of larger on-site PV installations.
