Check If Inverter/String is Suitable to be used for a specified number of Panels

* This calculator is a quick reference. It’s not intended as a replacement for AS5033 guidelines. Refer to the current AS5033 guidelines and local requirements from your electricity distributor.

Note: This calculator is using Australian Standard AS5033.2014 clause 3.1. Please refer to the newer version of AS5033.2021.

* Maximum voltage allowed for domestic installations is 600V, as of 20/06/2022, this could change with amendments to AS4777.1

GET THE FOLLOWING VALUES FROM THE INVERTER DATASHEET

Maximum DC Input Power in watts:
* For example if rating is 6kW, enter 6000
  
? The value must be greater than 0.

Maximum DC Input Voltage/Max. Voltage per MPPT:
* Maximum voltage allowed for domestic installations is 600V.
(As of 20/06/2022, this could change with amendments to AS4777.1)
  
? The value must be greater than 0.

Lower value of the MPPT:
  
? The value must be greater than 0.

Upper value of the MPPT:
  
? The value must be greater than 0.

Inverter AC Output power/continous output in watts:
  
? The value must be greater than 0.

GET THE FOLLOWING VALUES FROM THE PANEL DATASHEET

Panel Power in watts, Pmp:
 
? The value must be greater than 0.

Panel Voc at STC:
  
? The value must be greater than 0.

Panel’s temperature coefficient of Voc:
*Figure will be a negative %, please enter as a positive %. For example -0.28% will be entered as 0.28
  
? The value must be greater than 0.

Minimum Temperature expected at the site, in deg Celcius:
  
? The value must be betweeen -40 to 20 (inclusive).

How many Solar Panels in series on MPPT 1?
  
? The value must be greater than 0.

How many Solar Panels in series on MPPT 2?
