NHP DC Isolator Switch Recall

If your solar power system includes a ‘NHP’ branded DC isolator switch, you may be affected by a product safety recall notice. Certain models of NHP isolator switches have been recalled because they stay ‘ON’, even when the switch handle says it has been turned ‘OFF’. This can potentially lead to the electrocution of electrical contractors working on your system. To have a qualified electrician come and check if your NHP DC isolator switch has been recalled and needs replacing, simply contact Solargain today for immediate support.
