Valsa supplies three different types of inverters: grid ties, off grid/hybrid and micro grid inverters.

Off Grid/Hybrid

Off-grid systems are completely disconnected from the utility grid. These systems typically include a solar array, DC charge controller, batteries, bidirectional inverter and controls (with the possible addition of wind and other fuel generator alternatives for high load applications). In this configuration, energy is collected and stored to meet all local power requirements.

Grid Tied

Grid-tie is a common photovoltaic (PV) or solar system installation configuration in which electricity is generated by the PV system and routed to customer loads, offsetting the utility electrical demand of a business.

Micro Grid

A solar micro-inverter, or simply microinverter, is a plug-and-play device used in photovoltaics, that converts direct current (DC) generated by a single solar module to alternating current (AC). The output from several microinverters can be combined and often fed to the electrical grid.


Off Grid/Hybrid

Lynx - Axpert Inverters (Off Grid)

Axpert MKS is equipped with MPPT solar charge controller to maximize and regulate DC power from the solar array for charging the battery bank, providing reliable power conversion in compact size.

Grid Tied Inverters

Fronius Primo

The Fronius Primo in power categories from 3.0 to 8.2 kW. This single-phase, transformerless device is the ideal inverter for private households. SuperFlex Design provides maximum flexibility in system design, while the SnapINverter mounting system makes installation and maintenance easier. The communication package included as standard, with WLAN, energy management, several interfaces makes the Fronius Primo a communicative inverter for owner-occupiers.



Fronius Symo & Eco Range

Boasting power categories ranging from 3.0 to 20.0 kW, the transformerless Fronius Symo is the three-phase inverter for systems of every size. Owing to the SuperFlex Design, the Fronius Symo is the perfect answer to irregularly shaped or multi-oriented roofs. The standard interface to the internet via WLAN or Ethernet and the ease of integration of third-party components make the Fronius Symo one of the most communicative inverters on the market. Furthermore, the meter interface permits dynamic feed-in management and a clear visualisation of the consumption overview.
