The challenge
What the client needed
Our solution
What we delivered
PEC integrated a 20 kW / 40 kWh indoor BESS with the existing 250 kW PV, and designed the EMS in-house so the client could configure how the battery and PV work together.
Why PEC
Why this project chose PEC
Here the value sat in the controls more than the battery. PEC's in-house EMS let Toyota Tsusho set the charge, discharge, and PV logic to suit the building.
Outcome
What happened in production
The BESS works with the office's solar under PEC's EMS; it went live in September 2024.
