Microtek inverter circuit

Types of Microtek Inverter Circuit

Off-grid Inverter Circuit

An off-grid inverter circuit allows a person to derive power from a battery, which has been charged by an external source. The external sources may be wind, solar, genset, etc. The off-grid systems are regarded as autonomous energy systems where, even without central power, the users still have the power. Such systems are very useful in remote areas where there is no connection with the traditional electrical network.

Grid-tie Inverter Circuit

The grid-tie inverter circuit connects directly to the utility grid. This kind of inverter does not use batteries. They generate and supply electrical power to the grid using solar or another renewable energy source. When the power produced is more than the power consumed, an excess is fed back to the grid. These inverters comply with net metering, thus allowing utility customers to reduce electricity bills.

Hybrid Inverter Circuit

There are features of both the off-grid and grid-tie inverter circuits in hybrid inverter circuits. They have battery backup systems for storage of excess energy during low consumption periods, which can then be used at night or when the grid power is unavailable. The hybrid inverters can automatically switch between the grid, batteries, and renewable energy sources, depending on the operational settings and availability.

This actually provides more flexibility in system design and operation. It is especially useful to customers who prefer renewable energy solutions but require a more reliable backup power source due to grid outages.
