KOSTAL solar inverter
accessories

Our KOSTAL solar inverters are factory-fitted with a number of features, including interfaces for integrating them into a Smart Home, built-in data loggers and much more. But we also offer various accessories for you to optimise your photovoltaic system or PV inverter even further. You can order the majority of our range of accessories quickly and easily from the KOSTAL Solar online shop.


Dynamic self-consumption control with the PIKO BA Sensor

It is the law in Germany that it must be possible to limit the power made available by the PV system at the feed-in point either to 70% of the maximum generator power or, if required, to another percentage defined by a grid operator. The PV feed-in capacity is usually restricted by a ripple control receiver.

However, to enable you to utilise the full power of your photovoltaic system, we offer the PIKO BA Sensor for systems up to 30 kW as an attractively priced alternative to the ripple control receiver or a fixed limitation to a particular percentage.

The PIKO BA Sensor is used, amongst other things, to determine the power actually consumed within the home and to visualise it in the KOSTAL (PIKO) Solar Portal. The inverter's smart active power control function takes this self-consumption into account and adds it to the power generated by the inverter (up to 30% max.) until the set limitation threshold (70%) is reached at the network node. 
So, the PIKO BA Sensor allows the inverter to regulate its output power dynamically, rather than sticking to a rigid default setting. If you have a battery storage system, you are also in a position to store the energy not currently being consumed and to use it later for self-consumption. The energy generated can therefore be distributed ideally between the home, battery and public grid, enabling you to exploit your solar power to the full.

PIKO Sensor – monitoring the functionality of a PV system

The PIKO Sensor measures the temperature and irradiation at the solar modules, so you can compare the real irradiation and temperature conditions with the performance data of the PV system. Such a comparison means you can ensure the PV system is running to its full potential.

The following values are measured with the PIKO Sensor:

  • Irradiation
  • Ambient temperature
  • Module temperature

Especially convenient: the measuring values can be visualised via the free KOSTAL (PIKO) Solar Portal.


Safe and secure project business – accessories for the PIKO 36 EPC

Various accessories are available that make the PIKO 36 EPC project inverter even safer; for example, you can purchase optional overvoltage plug-in modules for both the DC and the AC sides. The same applies to the RS485 and network (RJ45) communication.
What's more, a fan cover can be retrofitted to prevent large pieces of debris (branches, leaves, etc.) from falling into the cooling channel and having an adverse effect on cooling performance or blocking the fans.


External battery connections for the PIKO BA

The PIKO BA battery inverter is opening up a whole new world of battery connection options; so now, the BYD B-Box H high-voltage battery can be used instead of the fortelion lithium battery, thanks to the RS485 interface card. 

Reliable energy thanks to the PIKO BA Backup Unit

What would work today without electricity? Practically nothing. The smart PIKO BA Backup Unit makes sure that your entire home will still have electricity even if there is a power cut. You experience no inconvenience and it will only be a matter of seconds before all your household appliances are back up and running: you can watch TV, cook and the heating still works.

Expand the PIKO BA System so it is customised to your exact needs and your family is never left in the dark. The PIKO BA Backup Unit is a very simple way to extend and upgrade your storage system.
