Review of Grid Connection Guidelines:  

Especially for grid-connected generation facilities, there are a wide variety of local connection requirements worldwide regarding grid safety for low- and medium-voltage grids. Benefit from our expertise in a wide range of regulations.

We test and certify in accordance with international standards!
VDE 0126-1-1-1, VDE-AR-N4105, VDE 4110/4120/4130, CEI 0-16/21, EN50549-1, EN50549-2, EN 50549-10, IEC 61727, IEC 62116, G98/G99, AS 4777.2, etc.

Performance Tests: Efficiency:

An important quality criterion for the cost-effectiveness of a PV system is the efficiency of the inverter. In our laboratory, we have the necessary expertise and state-of-the-art measurement technology to perform efficiency measurements on inverters with the highest precision.

We test and certify according to international standards!
EN 50530, IEC 61863

Battery Testing:

Many product standards and regulations for end-user devices require that lithium-ion batteries be tested and certified. Kiwa Primara GmbH operates an accredited testing laboratory in Kaufbeuren for testing lithium-ion batteries.

We test and certify in accordance with international standards!
UN38.3, IEC 62281, IEC 62133, IEC 62619, IEC 62620, IEC 62660, IEC 60086, IEC 61427, IEC 61960-3, IEC 62984, IEC 63056, IEC 63057, RTCA DO-311, UL 2271, UL 1642, UL 2054, UL 9540, UL 1973, etc.

Environmental Testing: 

PV components are often exposed to extreme environmental conditions. Environmental simulation tests—such as climate simulations, shock and vibration, IP/IK tests, salt spray corrosion tests, life cycle tests, aging tests, etc.—on components identify design weaknesses as early as the development stage and prevent costly redesigns and failures in the field.
