Kostal PIKO MP plus 3.0-1 3kW Solar Inverter is a flexible 1-phase inverter. Who says small photovoltaic systems aren’t worth the effort? The PIKO MP plus will show them a thing or two. The Kostal PIKO MP plus covers power classes between 1.5-4.6 kW.  The solar pv inverter can be used together with just three solar modules which makes it ideal inverter for small solar photovoltaic systems.

The Kostal PIKO MP plus 3.0-1 3kW Solar Inverter delivers extremely stable yields and its wide input voltage range provides numerous wiring options for the PV modules.  The solar inverter can be connected both as a PV inverter or simply can be installed on the AC side* as storage inverter for an existing system. Adding the KOSTAL Smart Energy Meter* allows the inverter to be used to store energy* without an additional inverter.

In the context of residential solar+ energy storage systems, a hybrid inverter (sometimes referred to as a multi-mode inverter) is an inverter which can simultaneously manage inputs from both solar panels and a battery bank, charging batteries with either solar panels or the electricity grid (depending on which is more economical or preferred). Their capabilities may go beyond this however – some devices also handle inputs from wind turbines, generators and other power sources.

10 to 20 years
Typically, grid connected inverters have a lifespan ranging from 10 to 20 years. You should expect most good quality units to last 10 years minimum. Solar inverters have warranties ranging from 5 to 12 years with an increasing number of manufacturers offering pay for service warranty extension up to 20 years.
