Make sure that existing wiring is in good condition and that wire is not undersized.
Never touch either the positive or negative pole of PV connecting device.
MAINS , battery and PV supply has been disconnected.
CAUTION-RISK of electric shock from energy stored in capacitor, Never operate on the
inverter couplers, the MAINS cables, Battery cables, PV cables or the PV generator when
power is applied. After switching o ffthe PV , battery and Mains, always wait for 5minutes
and MAINS couplers.
Measure the voltage between terminals UDC+ and UDC- with a multi-meter(impedance
at least 1Mohm) to ensure that the device is discharged before beginning work (35VDC)
system (LPS) when separation distance is kept.
To protect the DC system, surge suppression device (SPD type2) should be fitted at the
generator, if the voltage protection level (VP) of the surge arresters is greater than
To protect the AC system, surge suppression devices (SPD type2) should be fitted at the
main incoming point of AC supply (at the consumer's cutout),located between the
inverter and the meter/distribution system; SPD (test impulse D1) for signal ine accord
ing l to EN 61632-1.
DIMENSION
1.When PV, Grid, Battery is available:
A. On charge time, solar energy will charge battery as first priority. The excess
energy will supply power to the loads.If solar energy is sufficient to supply loads
and charge battery,and If there's still some extra energy, then the excess power
will feed the power to grid
B. On charge time, solar energy will charge battery as first priority.then the excess
solar energy will supply power to loads.If solar energy is not sufficient to charge
battery and supply loads, grid will supply all the connected loads with solar energy
together.
C. On discharge time, solar energy provides power to the loads as first
priority, if solar energy is sufficient to supply loads ,and if there's still some
extra energy from solar energy ,then the excess power and battery will
deliver the power to the grid at the same time.
D. In the period of no charge or discharge, the solar power supply loads at
first priority , excess energy to the grid.
2. When Grid, Battery is available(PV is disconnected):
A. On charge time, grid will charge battery and supply power to the
connected loads at the same time.
B. On discharge time, if load power is less than battery power, battery will
supply power to loads as first priority, the excess power will be feed to grid.
C. On discharge time, if load power is more than battery power, battery and
grid will supply power to the loads at the same time.
Work modes : Peak shift
1.When PV, Grid, Battery is available:
A. Solar energy will charge battery as first priority, if solar energy is excess,
the excess power will supply load. If there's still some extra energy, then the
excess power will feed the power to grid .
B. Solar energy will charge battery as first priority, if solar energy is excess,
the excess power will supply load.If solar energy is not sufficient to charge
battery and supply loads, grid will supply power to loads.
2. When Grid,Battery is available（PV is disconnected):
Grid will supply power to load and charge battery at the same time.
