Which inverters can be used with DualSun SPRING & FLASH panels?
When choosing the inverter that will transform the DC electricity (direct current) of the DualSun panels into AC electricity (alternating current), i...
How is the microinverter mounted to the DualSun FLASH AC panel?
The IQ7 Enphase microinverter is mounted on a self-locking slide plate on the rear panel of the DualSun FLASH AC module.   The FLASH AC panel is deliv...
Should I use a centralized inverter or microinverters ?
In terms of costs, centralized inverters are generally recommended for installations over 3kWp and microinverters for installations under 3kWp. Microi...
What are the technical characteristics of DualSun electric cables ?
The electrical cables fitted to the DualSun modules have the following technical characteristics: Cable section: 4mm² Permissible voltage in the condu...
Are DualSun hybrid panels compatible with standard photovoltaic panels from an electrical point of view?
DualSun panels were designed to be compatible with most PV electrical equipment commonly used in solar installations.
Is it possible to connect panels of different powers on the same inverter?
No, even if this connection is technically possible, we do not recommend connecting separate power panels in series on the same inverter.   If such...
Do I need Internet access to configure Envoy with Enphase microinverters?
Yes, it is necessary to have Internet access to set up Enphase microinverters with the Envoy gateway. However, there is no need for a very fast connec...
Is there a minimum distance between the microinverter and the roof, as well as between the microinverter and the DualSun SPRING panel?
YES, a minimum distance must be respected as no element fixed on the rails, for example micro inverter or optimizer, must be in contact with the back ...
What are the electrical connections on DualSun panels?
The junction boxes of DualSun modules have MC4 connectors (Stäubli MC4 EVO2). These connectors are compatible with all microinverters with MC4 connect...
Can Enphase M250 and IQ7 Microinverters be connected?
Yes.   Enphase micro inverters M250 and IQ7 can be connected in series on the same line: With junction box between cables Engage M250 and IQ7 (i...
Which cable section should be used to connect the panels electrically to the grid?
Section of the cables for all Dualsun SPRING and FLASH range is 4.0mm².  This section has been calculated according to the intensity of the current (A...
What is the maximum impulse voltage (Uw) of our FLASH 375 Half Cut White module ?
The maximum impulse voltage of our FLASH 375 Half Cut White panels is 20 000V. This data is taken from the IEC certificate:   To go further : What a...
What to do in case of untimely circuit breaking on an installation equipped with DualSun panels?
Untimely circuit-breaking in an installation may be due to leakage currents that are too high, triggering the differential. Leakage currents can have ...
Is it possible to self-consume the photovoltaic production when the low-voltage main switchboard is powered by a generator and not by the electrical grid?
Yes. Whether with a centralized inverter or microinverters, it is possible to self-consume the electricity produced by the photovoltaic solar panels w...
