Grid Protection Products
The CTP grid box is a turnkey grid protection solution. The CTP grid box is manufactured and pre-programmed to meet the specific requirements of each of Australia’s DNSPs.
The Grid Box is installed between the PV inverters and site’s main switchboard. This provides a “plug and play” grid connection package for solar installers, retailers and PPA providers. We seek to provide products that assist our clients in obtaining grid connections quickly and with minimal delay and cost implications.
Our larger grid boxes for systems more than 100kW include a revenue-grade, NMI approved meter and provide ongoing access to an integrated energy trading platform.
