Sputnik Engineering is showcasing its new SolarMax P series of inverters for solar plants up to 6kWp at Solar Power UK in Birmingham. The Swiss company’s P-series offers efficiencies of up to 98 percent and SolarMax believes that its solution offers maximum reliability, comfort and flexibility for all small-scale solar arrays in the UK market. 

The Swiss company has focused on providing the most flexible application options and best-possible connection ease. 

The SolarMax 4000P and 5000P devices sport two MPP trackers with an input current of 10A in each case that can be operated both in dual and in single tracker mode. With the help of the dual tracker concept, difficult conditions such as east-west arrangements or an odd number of modules can be handled without any problems. This way, it is possible to utilise the entire roof surface area ideally for power generation and to achieve the highest possible yields. Yield losses caused by partial shading can also be minimised by using the dual trackers.

The SolarMax P inverters are also cooled passively. The heat generated during operation is dissipated vertically by means of natural convection. All the inverter requires for this is to be attached to a wall in order to bring about the required chimney effect and to provide for permanent cooling. SolarMax believes that passive cooling makes the devices less prone to malfunctions or failures and, thus, reduces the risk of yield decrease.

Olaf Geistlinger, Senior Product Manager for the SolarMax string inverters, said: “Regarding inverters, safety and handling range amongst the most important quality features, along with the performance. With the P series, we first and foremost wanted to facilitate installation and commissioning of smaller plants. Handling the inverters is particularly simple and, thus, time- and cost-saving. Integrated communication features and customer-specific configuration options provide for further advantages for system operators.”
