How Do I Know If My Inverter Is Part Of This Recall?

If you own the product pictured below, your inverter is included in this recall. The first step to quickly determine if your inverter is potentially included in this recall, is to look at the front display panel of your inverter.

If the brand name printed on the front of your display panel reads “Eltek,” and the model designation is “THEIA” and “HE-t, you should immediately stop using these inverters by (1) first turning the disconnect switch on the front cover to the vertical off position, and then (2) switching off the circuit breaker for the unit. Please continue reading below to provide more information about your recalled unit.

IMPORTANT: Please note if the brand name printed on the front display of your inverter switch does NOT read Eltek, your unit is not included in this recall and you do not need to register.
