All About Inverters

The Inverter is the workhorse of a solar or a battery system. There are a range of differing functions available from different models. The Inverter needs to be selected to fit the customer’s requirements. `

When selecting an inverter, it is important to consider:

How Long is the warranty (Can be from 1 year to 10 years) ?

Does the warranty cover parts and labour, or just parts ?

The inverter’s efficiency is far less relevant these days as they are all hitting similarly high efficiency targets

Can I continue to use the power in the event of grid failure ?

Can I continue to use the Solar panels in the event of grid failure ?

What fom of backup power is provided,  Emergency Power Supply (E.P.S.) or Uninterrupted Power Supply (U.P.S.) ?

What is the difference between E.P.S. and U.P.S. ?

Is the inverter battery ready ?

INVERTERS FALL INTO DIFFERENT CATEGORIES

SINGLE AND THREE PHASE STRING INVERTERS

THIS REPRESENTS THE MAJORITY OF EXISTING SOLAR INSTALLATIONS

MICRO INVERTERS – A SMALL INVERTER ATTACHED TO EACH SOLAR PANEL

SINGLE AND THREE PHASE HYBRID INVERTERS

NEWER TO THE MARKET ARRIVING WITH THE BATTERIES

SINGLE AND THREE PHASE HYBRID INVERTERS WITH IN BUILT BATTERY.

AC COUPLED BATTERY INVERTERS – FOR USE WITH OR WITHOUT SOLAR PANELS.

MULTI MODE INVERTERS MOSTLY USED ON STAND ALONE POWER SUPPLIES

CENTRAL INVERTERS

THESE USED TO BE THE STANDARD FOR LARGE SCALE GENERATION. HOWEVER, THE INDUSTRY IS MOVING AWAY FROM THESE AND ARE EMBRACING LARGE SCALE STRING INVERTERS INSTEAD.
