Central Protection Unit (CPU) or Network Protection Unit (NPU) are required for systems with inverters larger than 30 kVa. The units act as secondary protection in the case of grid imbalance or fluctuations.
We custom build our CPUs to suit your requirements. We use ABB and ComApp equipment. Our boards can be integrated with export limiting and wireless switching. Every board is programmed and injection tested before delivery. All you need to do is wire them in and switch them on. All boards are designed and built by CEC accredited electricians in Albury and delivered to your preferred location. We can do injection testing on site.
If the install is more than (100Km from Albury) Please contact us for a quote.
