Repurposed 30kW 2 hour System for CEWh nears Completion

Community Energy Whāingaroa, a local Community Energy organisation contracted us to build them a BESS (Battery Energy Storage System) to work in partnership with their freshly comissioned 38kW pV solar array at Xtreme Waste. Specs are:

Hardware

• 5 x 2013 Leaf Batteries

• 1 x 30kW inverter

• Several computers

• Control/protection systems.

Software

• TIML custom BMS Controller. This communicates with the original Leaf BMS computers, the inverter, the Energy Management System (EMS). It also controls the contactors and safety disconnects.

• TIML custom data logging to database

• TIML custom Energy Management System (EMS) modified from Open Source OEMS

((We are awaiting approval from the local electrical lines company & electrical inspector signoff then we will be officially running with our prototype. Once its running nicely we’ll be looking for investors to scale the enterprise. Exciting times.

As can seen there’s plenty of room to scale and we have designed for this.))
