Project 2
Site: Primary School, Western Cape South Africa
The client is a renowned School, one of the top primary schools in the city of George with over 1200 pupils. The school prides itself on fostering a conducive learning environment, but like many institutions, they faced the ongoing challenge of high electricity costs and the risks of power outages that could disrupt daily activities and classes.
- 90kVA Victron Energy Quattro inverter/chargers (6 x 15kVA)
- 100kW Huawei 100KTL SUN2000 grid tied inverter
- RS450/200 Victron Energy solar charge controller
- 100kWh Freedom Won battery
- 182 x 550W Trinasolar PV modules (100.1kWp)
Our comprehensive Solution
Innovative System Design:
We opted to pair a 100kW Huawei grid tied inverter with the 90kVA Victron Energy Quattro inverter/charger cluster. The Huawei inverter is not only cost effective but also have ten MPPT’s making it very efficient, especially during cloudy conditions or times with shadow casting. While the Victron Energy inverter system originally was not compatible with the Huawei inverter, we successfully integrated the inverters by making use of a Programmable Logic Controller (PLC) that we programmed in-house. This not only ensured system reliability but also helped optimize battery and energy management.
Arbitrage Control for Peak Usage:
To further reduce costs, we implemented arbitrage controlling, which efficiently minimized the school’s peak tariff time electricity consumption.
Exporting Excess Solar Power:
The system allows for excess solar power to be exported to the grid, generating credits and further offsetting the school’s electricity bill.
