Quality And Performance
Fronius inverters show great efficiency that reaches 98%. Almost no energy is lost in the process of conversion. The installation is easier with Austrian inverters being up to 50% lighter than comparable ones.
The manufacturer made sure that its product is ready for the harsh conditions of the real world. Every Fronius inverter undergoes 13 extensive endurance tests. Devices have to be able to endure extreme temperatures, freezing, high humidity, dust and dirt. The company has been certified in accordance with ISO 9001 for over 20 years already which means compliance with the highest quality standards.
Warranty And Service
Most of Fronius inverters come with a 10 product warranty. It’s a good number, given the fact that the inverter is the most vulnerable part of a solar system and its lifetime generally ranges from 10 to 20 years.
Every Fronius solar inverter is equipped with on-board Wi-Fi which connects to the house network. Fronius Solar.Web platform makes it easy to monitor the production and manage the settings.
What to look for when choosing a Fronius solar inverter
When you are looking for an inverter, make sure that it fits your system. First, grid-tie inverters are designed for grid-tie systems and will not work with, for example, RV or boat installations. The DC rating of your inverter has to be comparable to the DC rating of your array. If the combined power output of your panels greatly exceeds the capacity of your inverter (say, by 50%), then the clipping starts and you lose a lot of power.
FAQ
Q.: How to prolong the lifetime of my inverter?
A.: Pick a dry cool dark room for an inverter with enough free space around it — garage is perfect. Clean air intake filters occasionally, wipe the dust off of it and check the screen for error messages.
Q.: Do I have to get an inverter?
A.: For residential systems inverters are mandatory — most of your home appliances just can’t make use of DC from solar panels. In mobile installations, like an RV or a boat system, an inverter can sometimes be omitted.
Q.: Are there any other functions of an inverter besides turning DC to AC?
A.: Inverters maximize production of your array, serve as a safety device and interact with the grid.
