Please notify me when you install the lightning system

[Joj]

I'd be grateful if someone could fix the proper way to send the following email to the client:

Please see the attached proforma invoice for the repairing inverter (twice it has been broken down due to lightning strike). Please notify me when you install the lightning system protection so that I may send a technician to your home to install the inverter.

Say:

It has broken down twice due to lightning strikes.
