FAQs 6

How does a solar inverter work?

Apart from the orientation of your solar panels and batteries, your solar panels should directly connect to your charge controller, as this is where voltage is regulated so that your panels can properly charge your batteries. Wires should then run from your charge controller and split into your batteries and into your inverter.

How does a photovoltaic system work?

The heart of a photovoltaic system is the solar module. Many photovoltaic cells are wired together by the manufacturer to produce a solar module. When installed at a site, solar modules are wired together in series to form strings. Strings of modules are connected in parallel to form an array.

How to wire solar panels together?

Wiring solar panels together can be done with pre-installed wires at the modules, but extending the wiring to the inverter or service panel requires selecting the right wire. For rooftop PV installations, you can use the PV wire, known in Europe as TUV PV Wire or EN 50618 solar cable standard.

What is a solar panel wiring guide?

This Solar Panel Wiring Guide is designed to help commercial developers, off-grid system integrators, and solar professionals clearly explain and plan wiring layouts that directly affect system performance, safety, and reliability.

How do I connect solar panels in series?

Connect solar panels in series by following the steps in our “wiring solar panels in series” section. Connect solar panel strings in parallel by using a connector known as MC4 T-Branch Connector 1 to 2, following steps similar to those in our “wiring solar panels in parallel” section.

How do PV panels work?

Each PV panel plugs into its dedicated inverter. These are just push in connections. Each inverter just plugs into the next inverter. You can connect up to 15 inverters in a row just plugging one into the next. These are simple push in connections. The power from the last inverter goes to a junction box mounted at the array.
