8. Electrical Configuration
Photovoltaic (electric) systems operate automatically and require very little day-to-day supervision. The solar
array generates DC electricity whenever light falls on it similarly the inverter automatically turns ON as soon as
there is sufficient energy from the solar array to efficiently convert this into grid.
It is recommended to use a suitably rated isolator (DC switch) to interrupt the current flow before disconnecting
the connectors.
Caution:
The module is rated to operate at potentially lethal DC voltages which have the potential can cause severe electrical
shock, arcing and fire hazards. Whilst some solar modules, manufactured by Maysun Solar, are certified to operate up to
1 000V DC (For MS.**, to 1500V DC) always check the module label to confirm the actual rating of your product before
making connections.
8.1 Fusing
When fuses are fitted they should be rated for the maximum DC voltage and connected in each, non- grounded
pole of the array ( i. e. if the system is not grounded then fuses should be connected in both the positive and
negative poles).
The maximum rating of a fuse connected in series with an array string is typically 15A but the actual module
specific rating can be found on the product label and in the product datasheet.
This fuse rating value also corresponds to the maximum reverse current that a module can withstand (when one
string is shaded then the other parallel strings of modules will be loaded by the shaded string and current will flow)
and therefore impacts the number of strings in parallel.
8.2 Inverter seletion and compatibility
When installed in systems governed by IEC regulations, Maysun Solar modules normally do not need to be
electronically connected to earth and therefore can be operated together with either galvanically isolated ( with
transformer) and transformerless inverters.
Potential Induced Degradation (PID) is sometimes observed in PV modules due to a combination of high
humidity, high temperature and high voltage. PID is most likely to cause degradation under the following
conditions:
a) Installations in the warm and humid climates
b) Installation close to a source of continual moisture, such as bodies of water
To reduce the risk of PID, we strongly suggest that modules feature Maysun Solar’ s Anti- PID technology,
which can be applied to any Maysun product. Alternatively, we recommend the use of an inverter that includes a
transformer as well as proper grounding ofthe negative DC leg ofthe PV array.
