We had some  lightening strikes last night and my 5.6 KVA unit has no lights on the controller.  The 7.5 amp fuse was blown and replaced but we still have no LED.  Battery was checked and its is good.  Any other areas I should check to get the controller back on?

I have 12V on both R 13 (Red Wires) going to the controller so it seems I have a bad controller.

Lightning is death on controllers, I think you have it figured out.

I thought T1-T2, N1-N2 fuses would have protected it from spike on the grid.  The spike came via the grid connection.

Fuses blow on high current, not high voltage of short duration.  Surge protectors are used to control voltage spikes.  That said, nothing can protect against a direct lightning strike.

Even if it does not strike the grid I have had bad results from just the static electricity in the air right after the strike, my HVAC zone panel didn't like it but I was able to power it down and re-set it.

Even the best whole house surge suppressors cant protect from lightning strike.. thats just life.

I was thinking of installing some whole house suppressors.  I use my generators in the Caribbean where we are 230V 50 Hz.  We only have  a Live and Neutral coming from the grid.  Can you recommend any?
