What is a solar panel inverter?
The solar panel inverter is essentially the heart of any solar panel system. The inverter is responsible for taking the energy produced by the solar panels, and converting this to electricity that can be used by your home and the national grid. The energy produced by roof solar panels is direct current, and this has to be converted to grid accepting alternating current. There are different sizes and types of inverter that suit different solar panel systems. These include:
Solar PV Systems
Here at ERG we are Preston’s solar panel experts, and we work across the country to provide affordable and effective solar panel systems. Every solar panel system consists of different components. The panels themselves are incredibly important, but they would be useless without the connected inverter.
A solar panel system is the term used to describe all of the components that work together to provide solar power to your home. The components include: the solar panels, the inverter and the battery.
Additional Solar PV products you might consider…
Solar iBoost
Solar iBoost+ fits quickly and neatly into your airing cupboard,
simply wired between the existing fused spur and immersion heater.
No need even to change your standard 3kW immersion heater.
It responds rapidly to the varying home consumption and
changing weather ensuring that only excess power is used.
Solar iBoost+ features connections for 2 immersions, switching
between them automatically to maximise electric water heating
systems.
PV + Optimiser
The new PV+ Optimiser means a faster return on investment for new and existing Solar PV installations.
What is the problem? When your Solar PV system is generating at optimum capacity, your inverter could potentially be in over-voltage mode and not generating at all.
What is the solution? By monitoring the income supply voltage, the PV+ Optimiser allows your inverter to stay in circuit for longer which prevents nuisance over-voltage shut down. The PV+ can reduce stress through voltage over heating and increase PV generation
