inverters
Grid tie and off grid solar systems use different types of inverters. What is a power inverter? An inverter is a critical part in any solar PV or battery system. The inverter takes DC power, either from your solar panels or batteries, and turns it into AC power, ready and usable for your loads and household appliances.

FAQ Inverters
A solar power inverter is one of the most important pieces of equipment in a solar energy system. It’s a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid and your home appliances use.
At night your solar panels and inverter power down. The inverter is not running overnight because it does not want to draw power. Instead it’ll wake back up when the sun shines in the morning.
Yes, if you are connected to an electrical grid, you can use solar panels and inverters without a battery storage system. These type of solar power inverters are called grid tie, on grid or string inverters.
While most solar power inverters come with a lifespan of approximately 5 to 10 years, they do require regular maintenance in order to ensure optimal solar PV inverter efficiency. Some of the inverters can efficiently operate up to 25-30 years as well. The lifespan of an inverter is determined by the operating temperature, the correct sizing of your solar panel system and the protection level used on your electrical board.

The main advantage that a three-phase inverter has over a single-phase power inverter is that it can transmit more power. A multi-phase system itself will produce power at constant rates within a load. The efficiency is also higher than in machinery that might be operated through a single phase.
A single-phase solar inverter has one live wire which connects to your home. While a 3-phase solar inverter has 3 live wires connected to your home. A 3-phase solar inverter sends the electricity evenly across the 3 wires which minimizes the voltage drop problem associated with a single phase power supply.
A solar installer needs to be mindful of clipping losses, and the power gain from overloading while overloading a power inverter. Clipping losses occur when the actual solar power production exceeds the AC output of the Inverter. The excess solar power beyond inverter ac capacity will be clipped or lost.
By oversizing the array, you will make better use of your inverter’s capacity, producing more power overall. You want to find the “sweet spot” where you get the most overall production possible per amount spent on your system – even if that means clipping a bit more power.
The size of your solar panel system should not exceed 15-20% of your solar power inverter rated power.
All the way around, the larger size of an inverter on a smaller solar panel system has no negative effects. Actually your inverter will live longer.
Undersizing a power inverter has become a best practice. A properly undersized solar system will produce the best power output for the system owner. It can also save the homeowner money if it enables them to avoid a main panel upgrade.
Though this is true, IF your system is properly sized by a solar installer an undersized inverter will live less, resulting extra inverter replacement costs for a homeowner.
In systems using a grid-connected (grid tie) solar power inverter, the inverter is usually sized to match the solar array. For example, if you have a 5kW solar array, then you would install a 5kW inverter; though we always recommend to install a bit more panels to overcome the efficiency loss of your solar panels, inverter and other electrical components installed in your system.
