Description

The trainer is composed of two solar panels that power storage batteries. The panels are installed on a mobile structure that allows the panels to be placed outside. They can be tilted at different angles to study the influence of the angle on solar production. An inverter will transform the DC voltage of the batteries into an alternating voltage of 230VAC to power the water pump.

A dimmer allows you to adjust the pump's rotation speed and the energy consumed.

Integrated measuring devices make it possible to analyse the overall operation of the system.

The rugged design of this equipment makes it perfectly suited for use in a school setting.

Its anodized aluminum structure on wheels gives it a very high robustness as well as great flexibility of integration into your premises. The manufacture of this equipment complies with the European Machinery Directive
