two Installation instructions

1. Unpacking inspection

1.1 Open the package of the equipment and check the accessories, including one main engine, one user manual and one certificate of quality.

1.2 Check whether the inverter is damaged during transportation. If any damage or missing parts are found, do not turn on the inverter and inform the carrier and distributor.

2. Installation Precautions

2.1 Installation of inverters shall be operated by professionals or assisted by local distributors.

2.2 Appropriate protection measures shall be taken when transporting the inverter; When the inverter is moved from a low temperature environment to a high temperature environment, water droplets may appear. Before use, it should be completely dried to ensure safety.

2.3 Do not expose the inverter to damp, flammable and explosive or dust gathering in a large number of harsh environment; Do not cover and block the vent, reserve more than 10CM air circulation clearance around the inverter; In order to have good heat dissipation;

2.4 First ensure that all the circuit breakers on the panel are placed in the closed position, please take off the ring, watch and other metal items when connecting the battery, and pay attention to the battery polarity, terminal voltage and inverter parameters consistent;

3. MPPT solar control inverter integrated machine introduction and description

1. Description of working status of solar controlled inverter

1.1 Introduction to the working principle

The controller provides intelligent charging management of the battery by solar photovoltaic array. The terminal voltage, ambient temperature and other parameters related to the battery capacity are sampled and calculated by microprocessor chip to achieve high accuracy control. The high-efficiency MPPT battery charging mode, to ensure that the battery works in the best state, prolong the service life of the battery;

An inverter is an AC power supply device that provides multiple protections. It can convert the dc energy stored in the battery into ac output to the load, and can also automatically output the mains to the load through the internal static and dynamic switch, and charge the battery at the same time (charging function is optional, should be determined according to the specific application requirements);

The inverter uses the power from the solar photovoltaic array preferentially, the inverter is in the battery work preferentially, the output ac running state; When the energy provided by the photovoltaic array exceeds the working energy of the load, the energy provided by the photovoltaic array meets the energy of the load and the remaining part is stored in the battery. When the pv array to provide enough energy load work energy, photovoltaic array to provide all the energy to load, is not part of the energy provided by the battery, when this kind of situation lasted (for example, night time), the energy of the battery down to low voltage alarm threshold (single section 12 V battery < 10.8 V), the load of the power supply automatically switch to the grid system, By the mains to provide energy, at this time the battery processing waiting for charging state; When the solar photovoltaic array replenicates the battery to the refill threshold (a single 12V battery > 13.5V), the inverter automatically runs on the battery and outputs ac power. The load energy is provided by the photovoltaic array and the battery, and the mains is in the standby state.

1.3 Block diagram of battery working and output AC running state

1.4 Block diagram of mains bypass operation Status

Description of mains bypass operation status:

When the inverter is in the following situation, it will automatically switch to the state of mains power supply;

1) Standby state;

2) Inverter output overload or battery voltage low;

3) The inverter circuit in the machine fails;

When the above situation occurs, the input power is directly sent to the AC output terminal through static and dynamic switch, and the load power is provided by the power supply;
