ELECTRICAL SAFETY
SAFETY REQUIREMENTS
The voltages and currents produced by a single module or modules connected in series (voltages are added
together) or in parallel (currents are added together) can be dangerous.
Note: Only qualified personnel should perform work on photovoltaic systems.
UNIQUE HAZARDS OF DC ELECTRICITY
PV modules generate DC electricity as soon as they are exposed to sunlight. Once the current is flowing,
breaking or opening a connection (e.g. disconnecting a DC cable from the inverter) can cause a DC electrical
arc. Unlike arcs occurring in conventional low voltage AC wiring, DC arcs are not self-extinguishing. They are
a potentially lethal burn and fire hazard, capable of creating high temperatures that can destroy contacts and
connectors.
EARTH FAULTS
Normally, the DC circuitry of the PV system is insulated from earth. An earth fault is a system fault where a
short circuit is formed between the DC circuitry of the PV system and earth. As the PV system owner, please
be aware of the current method of communication of earth faults on your system.
Solahart inverters are able to communicate an earth fault in three different ways:

Inverter display

Inverter built-in audible alarm

External alarm
– Email Alert

External alarm
– Audible or Visual Alarm
ACTIONS TO UNDERTAKE IN THE EVENT OF AN EARTH FAULT ALARM
1.
Limit access to all parts of the PV system
