INSTALLATION PROCEDURE, SWITCHING ON THE DEVICE
CAUTION! HIGH VOLTAGE.
CONNECTION WORKS SHOULD ONLY BE CARRIED OUT BY
QUALIFIED SPECIALISTS.
1. Recommended maximum total power of PV modules in the maximum power point
1.5kW should not exceed 2.5 kW.
2. PV modules are connected serially. Maximum current of PV modules in the maximum
power point should not exceed 10 A.
3. When installing connections of PV modules, assure that connection polarity is not
reversed.
4. When configuring the photovoltaic system, make sure that all photovoltaic system
components are operating completely within their permitted operating range. All
measures recommended by the solar module manufacturer for maintaining solar
module properties must be followed.
CAUTION! If connection polarity is reversed, damage to the device
is unavoidable.

place must not hinder natural ventilation of the device and be convenient to control it.
For precise readings we recommend to install temperature sensor on the top of the
tank.
8. Nectar Sun is suitable for indoor installation only.
9. The device must not be installed or operated above an altitude of 11,154 ft. (3400 m).
The maximum permissible DC voltage of the inverter depends on the altitude.
10. Disconnect the boiler from electricity grid and connect it to Nectar Sun.
11. Connect connectors of solar PV modules to the Nectar
Sun (see Fig. “Control
Elements and Conn
ections”
)
12. Connect Nectar Sun device to electricity grid.
