tried Inverter-warehouse, they sell ZJBENY, bur only deliver in their local area, any other suggestions, what and where to buy

Try Rubicon Montague Gardens. 

 

thanks @brianh, Rubican does stock them, what do most of you guys use, the 600 v or 1000 v

I use Citel DS240-130DC for surge protection on my PV Panels. This has a max DC operating voltage of 180V, but they have other voltages versions available.

I use Citel DS240S-230/G for surge protection on the AC connections to my inverter. This is rated at max operating voltage of 255Vac.

I purchased both of these from Rubicon just over two years ago. 

Note: Ideally you want to choose a protector that is rated slightly above your maximum panel/string voltage, but not too high - otherwise it offers less effective protection. 

[Edit] This protection is more than adequate for Cape Town, but may need a more robust solution for more lightning-prone areas of the country!

Thanks Nigel, I see all the combiner boxes with the 600 and 1000 v surge protectors, but what you say with us being n Cape Town, we can use less than 600 vprotectors, makes sense.
