The PIKO MP plus is extremely adaptable thanks to its power classes of between
1.5 – 5.0 kW, making it ideally suited to small photovoltaic systems on detached
homes, and it’s ready for use with just three modules or more. The single-phase
inverter delivers extremely stable yields and its wide input voltage range provides
numerous wiring options for the PV modules.
Combined with the KOSTAL Smart Energy Meter and the corresponding activation

The PLENTICORE plus has a solution for this: using the smart

high yields despite shading.
If you've got a smaller PV system, some of which is shaded,
you can use the PIKO MP plus because even the single-phase
device has the shadow management function, so you can enjoy
good yields even with small PV systems.
Will it cost me to convert the PV system when I replace
the inverter?
No, the new PLENTICORE plus is designed so flexibly that in
most cases it can easily replace the existing inverter like for like.
For example, it has an optimum voltage range, a wide variety of
interfaces and is available in five power classes. So, depending
on the solar module, 5 to 22 PV modules can be connected per
string. In a nutshell: the PLENTICORE plus is always the right
match.
The inverter can be replaced with great ease even in small PV
systems. The extended MPP range makes the PIKO MP plus
ideal for repowering. In addition, its wide input voltage range
allows numerous wiring options.
