For all your test equipment requirements

HT Italia SOLAR300N Solar Installation Efficiency & Power Quality Analyzer

HT Italia Logo

Multifunction Solar instrument designed to test single-phase and three-phase photovoltaic systems and analyse the mains quality in compliance with standard EN50160. (Voltage characteristics of electricity supplied by public electricity networks)

It carries out all tests required to verify the efficiency of single and three-phase PV systems. Testing PV systems requires the measurement of environmental and electric parameters.

HT Italia SOLAR300N tests single-phase and three-phase photovoltaic systems. For this kind of tests, it is necessary to guarantee simultaneity between power measurements carried out at the inverter and irradiation and temp

Typically, modules and inverters can be positioned several tens of meters away from the PV system, forcing the operator to carry out measurements in different places far from each other at the same time.

To carry out these operations, connections can be made by means of long cables or via radio connections, but both these solutions are not ideal.  Cables could hamper the operator’s movements or be a hindrance, while radio waves would be weakened by floors, reinforced concrete or metal structures, making communication impossible!

In order to avoid the above-mentioned problems HT Italia SOLAR300N is provided with a remote unit which is synchronised with the main unit. The remote unit is positioned next to the PV modules and it is connected there; it measures the environmental parameters needed (irradiation and temperature) making measurements comfortable and safe.

Useful Accessories and Software

MPP 300 increases the impressive features of SOLAR I-V by enabling recordings on the following PV systems:

Single/three-phase, single/multi-string (up to three strings), single-inverter and multi-inverter.

The management software TopView allows you to create professional reports, which can be customised by adding the company’s logo, the customer’s data, comments, etc.
