Solar Security: Shielding Your Inverter with VoltApex

As solar installations become more common in the industrial sector, so do inverter failures. Most inverters are destroyed not by the solar panels, but by surges coming from the grid. Because solar inverters use delicate power electronics (IGBTs), they have very little tolerance for voltage spikes. A VoltApex Isolation Transformer installed between the inverter and the grid provides a physical barrier that absorbs these shocks.

Preventing DC Injection

Another technical benefit is the prevention of DC injection into the utility grid. If an inverter malfunctions, it can leak DC current back into the AC system, which can saturate the utility's transformers and cause fires. The isolation transformer's magnetic coupling naturally blocks DC current, making your solar plant safer and more compliant with grid regulations.
