Tipa

The simplest boiler water heating system available on the market.

The set consists of 4 Kingdom Solar KD-M410H-108 Half Cell monocrystalline panels with a power of 410W each, an ECO Solar Boost MPPT-3000 3.5kW PRO converter and a complete 25 meter long cabling terminated on one side with MC4 connectors. and on the other with eyelet connectors for the converter.

The system is simple, it only requires the connection of 4 typical photovoltaic panels with an operating voltage of approx. 32V or the corresponding number of others and an energy receiver, e.g. electric boiler, underfloor heating.

The ECO Solar Boost MPPT-3000 PRO converter is equipped with an LCD display that continuously informs the user about the parameters of the PV installation, e.g.:
PV system voltage
electricity produced by PV panels
output power
total energy produced today
the total energy produced in the previous day
total energy produced (measured from the first switch on)
In addition, the display shows current events and detected irregularities in the form of text messages.

The maximum power of the system is 3.5kW, the converter has priority output number "1" and dependent output number "2".

This allows you to connect two heating devices, for example two boilers, one of which will heat first and the second when the thermostat of the first one stops receiving energy from the inverter. Thanks to the implemented MPPT function, the inverter automatically adapts to the performance of the heater and sets its operating point so that the energy received from the photovoltaic panel system is maximum.

installation instructions

The table you can find in the photos shows how to choose the optimal heater depending on the power and voltage of the PV system. Choosing the optimal heater guarantees the highest efficiency of the PV system for heating water.
As you can see, the actual performance of 230V heaters is strongly dependent on the PV system voltage, optimal heaters are marked in green, too weak in orange and too strong in red.
