Four Ways to Charge Inverter Batteries

The four charging methods of the inverter are as follows:
1. Photovoltaic (PV) priority: Photovoltaic (PV) gives priority to charging the battery. Only when there is no photovoltaic (PV) energy, the mains will charge the battery. This mode is suitable for users with relatively expensive electricity prices and low power supply requirements.
2. Main priority: The mains will give priority to charging the battery, and the photovoltaic will charge the battery only when there are no mains. This model is suitable for places where electricity is cheap but power outages are frequent.
3. The inverter charges the battery from the mains and photovoltaics at the same time. This mode is suitable for areas with low electricity prices and large demand for power supply.
4. Separate photovoltaic charging: no matter whether there is main power, only photovoltaic charging is used. This mode is suitable for users with high electricity prices and low electricity demand

How Important Is A Full Power Inverter

The output power of the inverter must be greater than the power used by the electrical appliance in order for the electrical appliance to operate normally. If the power of the inverter is insufficient, and the actual electrical power is greater than the actual power of the inverter, the life of the inverter will be reduced, or even cause the inverter to be burned out, and an inverter with a similar output power of 2000w will not be able to drive the rated power. This is the case for appliances with a power of 1500w.
When purchasing an inverter, you should carefully check whether the output power unit is W/KW or VA/KVA. The unit is W/KW is an active power, the unit is VA/KVA is apparent power, and active power = apparent power * power factor cosΦ (cosΦ is usually less than 1). Some unscrupulous manufacturers will deliberately confuse active power and apparent load power to mislead consumers. For example, 1000VA inverter, if the power factor is only 0.5, then its active power is only 500W. You will find that driving a 500W motor is no problem, but a 1000W motor cannot.
We refuse false standard power. The rated power of the inverter is 2000W, and the measured power is also 2000W, which can easily drive 2000W electrical appliances. Welcome to inquire and purchase!
