PowerSolar solar demo facility

PowerSolar’s solar demonstration facility, in Melbourne, is equipped with a total of 28 individual PV panels of 190 W each, providing a total maximum power of 5.3 kW. The PV array can be arranged in single-string or dual-string topology so as to demonstrate single and dual maximum power point tracking (MPPT). The demonstration laboratory has two inverters, both Growatt 5 kW units, one with a single and one with dual MPPT thus permitting installers to familiarise themselves with the advantages of dual MPPT systems for A-frame roofs.

The company markets Growatt transformerless inverters, currently with a maximum rating of 5 kW, and in order to service the solar energy system installer market, is able to provide product ex stock within a 24-hour period. Power Parameters maintains in its NATA-approved service laboratory a section specialising in inverter repair and MPPT calibration.

The Growatt inverters incorporate the latest developments in high energy density solid-state components, are transformerless and do not have fans, relying instead on good, convection-promoting designs. The construction of Growatt inverters is suited to the variable climate conditions of Australia, offering IP65-packaged electronics with complete protection against ingress of dust or powerful water jets.
