The benefit of understanding the nature of the fault is that it can cut down the time that the system spends offline. Rather than having to book an engineer to come and diagnose the fault, if we are made aware of what is wrong, and we know the inverter cannot be fixed, we can either make an immediate warranty claim or order a replacement inverter for immediate installation.
From a financial perspective, being aware of your systems status is of paramount importance. Put simply: if the system is off it is not making or saving you money.
Subject to when your array was installed, a 30kW inverter, off for 2 weeks in the summer, will mean you miss out on c. £800 of revenue/electricity savings.
With this in mind, if you are unable to check the system status regularly, it makes sense to install remote monitoring hardware and software. These systems send the realtime performance and status data to an online portal that can be viewed from anywhere in the world. Additionally, they can be set up to alert you to system failures or under production.
