How to Choose

A 20kW system is a significant investment, and a single surge reaching the inverter can be costly. This kit protects each of the two PV strings with its own DC MCB and DC SPD, and protects the AC output with a four pole MCB and SPD, all in a 20-way metal box with room for neat wiring. Choose the 40kA AC SPD for typical sites, or the 60kA option for exposed locations or sites where lightning is common. Have the earthing system checked, because SPDs only work well with a low-resistance earth.
