Keeping cool and connected: How Hoymiles HIT hybrid inverter supports smart offices in Thailand

In Thailand, one of Hoymiles' most trusted EPC partners is putting HIT to work in their own offices.

Sumitra – recognized as a Hoymiles Outstanding Installer for five years running – recently deployed a 10 kW solar system at their company headquarters and training center.

With high daytime energy demands from multiple air conditioning units and long operating hours, they needed a solution that could provide consistent, cost-effective power.

The result was a hybrid system combining Hoymiles' HIT-20L-G3 inverter with LB-5D-G2 battery storage.

Smart solutions, installed by the best

As one of the most experienced solar EPCs in the region, Sumitra specializes in end-to-end PV solutions, including system design, sales, installation, and after-sales maintenance.

So when it came time to upgrade their own training facility, they chose to test Hoymiles’ most advanced hybrid technology – putting the system through its paces in a real-world, high-demand environment.

Power that adapts to the workday

To meet the center's energy needs – including extended use of multiple air conditioning units – Hoymiles provided a hybrid energy system with:

• 1 × HIT-20L-G3 hybrid inverter – Energy hub in the system.

• 4 × LB-5D-G2 low-voltage LFP batteries – Store excess energy for better use.

• 1 × DTS-WL-G3 data transfer stick – Collect and transmit system data.

This 10 kW setup is designed to handle peak loads during the day and shift to battery power during outages or grid instability – a common challenge in regions with high energy demand.
