Preamble
Solar energy generated in excess of current needs is stored by the new modular lithium-ion battery ESS 3.0 / ESS 7.0 for later
use. BMZ GmbH is entirely focused on the high quality of its products. Production meets highest quality requirements and is
subject to permanent control of BMZ GmbH's quality management. It has successfully passed all the required approval tests.
1 Generalities
These Terms of Warranty shall not affect the statutory rights of the customer (warrantee), including but not limited to
supplementary performance, cancellation, reduction, damages. These Terms of Warranty apply in addition and supplementary
to the warrantee's statutory and contractual warranty rights.
The warrantee's statutory rights shall persist even if a case of warranty occurs and/or if the warrantee raises a warranty claim.
2 Warranty
BMZ GmbH provides its immediate/direct customer (warrantee) with the warranty that the products under this warranty are free
from defects in the product or its manufacture.
The warranty implies a performance of 5,000 cycles over not more than 10 years of use (fair value warranty).
The warranty shall not affect the obligations of customers who classify as entrepreneurs within the scope of Art. 377 of the
German Civil Code (HGB).
This warranty assumes a battery to be "defective" if its capacity drops below 60% of its
design capacity. (The design capacity is established at a battery temperature of 25 °C and with the battery being disconnected
from the other components of the energy storage system, i.e. from inverters and other consumers.)
This warranty is non-transferable.
