PLEASE NOTE !!!
If you have a voltage stabilizer at the input of the inverters please get a voltage monitoring system or protector ( AVS) connected after the stabilizer before the the inverter so that if there is a high voltage supply from the stabilizer at any time it will not be allowed into the inverter.
NEUTRAL TO EARTH VOLTAGE
If you have voltage between neutral and earth terminal then that is a problem.
Either the earth is bad or there is a phase reversal of the circuit.
- Note that the input and output neutral must be looped together at the connecting terminals of the inverter.
- A single Neutral cable is needed. The Neutral cable must not be controlled by any switch, breaker or change over control
- All solar panels must be installed facing the right direction – south
- Open circuit voltage (VOC) from all your panels should be about 80 vdc (Growatt 3kVA/24V) – 100vdc (Gennex 3kVA/24V)
- The inverter must be connected to a good earthing system.
- Do not power ON the inverter before you start configuration settings
- You must reconfigure the inverter before commissioning or power ON.

PV energy supply priority setting: 1
st Load, 2nd Battery
PV power will provide power to the load first and then charge battery. Feed-in to the grid is not allowed under this mode. At the same time, the grid relay is connected in Inverter mode. That means the transfer time from inverter mode to battery mode will be less than 15ms . Besides, it will avoid overload fault because grid can supply load when connected load is over 10KW.
PV energy supply priority setting: 1
st Battery, 2nd Load
PV power will charge battery first. After battery is fully charged, if there is remaining PV power left, it will provide power to the load. Feed-in to the grid is not allowed under this mode. At the same time, the grid relay is connected in Inverter mode.
That means the transfer time from inverter mode to battery mode will be less than 15ms. Besides, it will avoid overload fault because grid can supply load when connected load is over 10KW

FUNCTION OF THE CAPACITOR CONNECTED AT THE OUTPUT AND INPUT OF INVERTER EXTERNALLY.
OUTPUT .
Transient Voltage Suppression:
Sudden changes in load or other events can cause transient voltage spikes at the inverter output. A capacitor can act as a temporary energy storage device, absorbing these spikes and preventing them from damaging downstream equipment as well as the inverter.
INPUT
Power factor correction:
In AC systems, the current and voltage waveforms may not be perfectly synchronized, leading to a phenomenon called power factor. A low power factor indicates inefficient power transfer, resulting in higher energy costs and potential grid instability.
Adding a capacitor at the inverter input can help improve the power factor by storing and releasing reactive power, bringing the current and voltage waveforms closer in phase. This can lead to:
Reduced energy consumption Improved grid stability
Lower penalties from utility companies.

Either the earth is bad or phase reversal of the circuit.
- Note that the input and output neutral must be looped together at the connecting terminal of the inverter.
- A single Neutral cable is needed. The Neutral cable must not be controlled by any switch, breaker or change over control
- All solar panels must be on the same flat roof platform
- Please do not connect all the solar panels on a set of busbars and from bus bars to each inverter.
Connect each string or arrangement of solar panel design for each inverter directly to each particular inverter
- Open circuit voltage (VOC) from all your panels should be about 300vdc to 400 vdc.
- Solar breaker must be double pole high voltage DC breaker.
- The inverter must be connected to a good earthing system.
- Do not power ON the inverter before configuration setting.
- You must reconfigure the inverter before commissioning or power ON.
- Be sure that all your connections are correct and intact.
COMMISSIONING
- Switch on only battery breaker
- Switch on solar breaker
- Switch on utility input breaker.
- Reconfigure the settings of the inverter to the specification of the site.
- Switch on the power button on the inverter. Be sure there is no error code.
- Switch on the output or load breaker
- Switch the bypass control switch to allow the inverter power the available loads in the house.
SOLAR (PV) /EARTH TEST
PV TEST
1. Make sure that the solar breakers are switched off (completely isolated)
2. Turn your meter to DC voltage range for measurements
3. Take measurements between the solar cable coming from the roof and the inverter body or (earth )
4. P is positive. N is negative.E is earth.
5. Take the voltage measurements of the inverter solar inputs terminals when the inverter is running on battery or utility while the celebrities are in off state.
6. Send your results for evaluation.

EARTH TEST
Single phase
Get a capacitor of about 5uf 450v ac
Note that the capacitor is just a testing tool that will be disconnected after the confirmation test.☝🏼
Connect between LIVE and the EARTH
Use your digital voltmeter to measure the ac voltage between EARTH and the NEUTRAL
