There is one double pole DC circuit breaker isolating both DC positive & DC
negative.
The KwH meter shows an accumulative reading of the total power generated
and allows the user to monitor their green power production. LCD display
with 5 digits and 2 decimal places (i.e. 99999.99kwh).
After dark when the solar input is no longer available the Inverter will
automatically disconnect from the AC grid. This feature ensures that during
the night, the Inverter cannot consume any power whatsoever while
remaining idle. Upon sunrise the next morning when solar input becomes
available again, the PV edge will automatically reconnect to the AC grid and
begin generating power.
The PV edge automatically synchronizes to the AC grid, therefore the output
of multiple units can all be connected together, and they will all be
synchronized by the AC grid.
The optimum power level from the solar input depends on the available solar
modules. Even in cloudy weather with fluctuations in the solar radiation
level, the PV Edge constantly monitors and tracks the optimum operating
point to ensure maximum power from the solar modules is achieved.
The AC grid supply is constantly monitored for under and over voltage, over
and under frequency, and anti islanding conditions via active phase shifts.
The DC input is protected against over voltage, reverse polarity and over
current via very fast current limit control. Isolation between the DC input and
AC output is achieved via the Toroidal Transformer. The temperature of the
transformer and switching devices are continuously monitored. The Inverter
is fitted with a cooling fan, which is temperature controlled and only operates
when required.
When in Battery mode ( MPPT disabled) a maintenance cycle is performed
every 30 days. This is a short boost cycle for sealed batteries or an equalize
charge for flooded cells. In this mode the bottom LED will flash slowly until
the cycle is completed.
The Solar inputs of multiple unit Inverters are not to be paralleled.
