Types of Solar Systems

This is a brief explanation of the different types of inverters:

There are three main types of inverters. Those being;

• Grid Tie
• Backup / Storage
• Full Hybrid

The basic differences and features of each can be explained as follows:

Grid Tie Inverters:

• No Storage – This mean it can provide no power to Building when AC Supply not available.
• Power feedback to the supply is controlled via a Current Transformer

Backup Inverters:

• Building Distribution Board is Split into Essential and Non-Essential Loads
• In regards to Storage – Power is only sent to Essential Loads when AC Supply is not available.
• Power can not be fed back to the grid and Non-Essential Loads.

Full Hybrid Inverters:

• Building Distribution Board is Split into Essential and Non-Essential Loads
• In regards to storage – The power is only sent to Essential Loads when AC Supply is not available.
• Surplus Power feeds to Non-Essential Loads and AC Supply.
• Power is able to feedback to the supply control via a Current Transformer
