How to stick to the load, draw the grid and draw the grid?

Solar power is a system of panels that receive light that converts energy from sunlight into electricity. This power is a 1-way current that will pass through the Inverter to become an AC current put into use for home use.

The concept of load grip, grid tie and grid tie
1 / Load grip – Off grid – Independent system: Inverter will produce AC current with enough power for the family to use. The excess power will be loaded into the Acquy (Lithium Battery) battery. If the usable capacity is greater than the maximum capacity of the Inverter, the Inverter will disconnect itself and report an overload error. Can be used when the grid is out of power. Moderate investment costs. The device lifecycle is not long.
2 / Grid blending – Hybrid – Hybrid: Inverter will produce AC current with enough power for the family to use. The residual capacity will be pushed into the Acquy (Lithium Battery) battery. Setup can choose to stick to the load mode or blend into the National grid. If the usable capacity is greater than the maximum capacity of the Inverter, the grid will compensate itself for the lack of capacity. When there is a grid outage; the system automatically returns to load grip mode. This is the most optimal method. Can be used when the grid is out of power. However, the investment cost is high and the equipment life cycle is not long.
3 / Grid – On grid: Inverter will give AC current with maximum capacity. The family uses surplus, the system will push the excess capacity to the grid. Control this excess electricity with a 2-way clock. This form is very popular nowadays because there is a policy to support the installation of 2-way watches and EVN signs a contract to buy back this surplus capacity for 1,943₫/kW (price excluding VAT) for a period of 20 years; by transferring funds directly to the client's account after summing up the excess capacity at the end of the month. – Moderate investment costs. Cannot be used when the grid is out of power. Long device lifecycle.
P/S: A 2-way power meter is a meter that measures the number of in-dimensional power (using at night without solar power or insufficient solar power capacity, the grid power will automatically compensate) – the out-of-way electricity (when the solar power is over capacity will push out the grid). These two dimensions operate independently and are not deductible directly. Any dimensional capacity will be charged according to the price of that dimension.
