Possible malfunction on ESS handle:
important customer information for electrically skilled persons

Dear Sir or Madam,

During the latest quality tests on the Sunny Tripower range we have determined that during the pulling of the ESS handle a contact element can remain in the inverter and as a result the DC disconnection process is not correctly completed. This occurrence is very unlikely and only affects an older version of the ESS handle.  We would however like to inform you comprehensively and in good time. Along with personal communication we are making this web site available to you.

Here you will find further information in the form of FAQs.

If you have any questions or require further information you can of course also contact us at 00800 7627378423.


Yours faithfully,

SMA Solar Technology AG
