We strive to understand what your needs are. Do you have a particularly high performance high demand application? You will find it easy to recognize the new benchmark we have created in our Pro series. You receive performance with the latest innovations and upgrades that give you flexibility, power and peace of mind.

Along with the innovation of larger size wafer-based PV modules, ASW 25-40K LT-G3 series three-phase inverters are developed to be perfectly compatible with 182/210mm wafer-based PV modules which are frequently the model of choice in large-scale commercial, industry, and residential PV systems.

3 independent MPP trackers with up to 40A rated input current per MPPT enables dual unit installation with more flexibility for high power, bi-facial and large area PV modules.

With extra high power yield and lightweight design, the ASW 25 40K LT-G3 series delivers next level performance.

A wide MPPT range with 150% oversizing of PV array ensures high energy

Compact wall mounting with IP66 rated design delivers solid, long term performance against the impact of harsh environments.

Our smart cloud-based AISWEI app provides user-friendly tracking wherever you are.
