JAN 23 13 Best Grid Tie Inverter with Battery Backup

With the invention of solar inverters operations of solar panels became much easier. Now, the panels are safe from damage and even the appliances and battery connected to the inverter are safe from certain power issues. A solar inverter can be used in all 3 forms grid, on grid, and hybrid. Basically, manufacturers nowadays provide specialized inverters for particular uses. You must have heard about grid tie inverters. Are you thinking of buying one and looking for the best grid tie inverter with battery backup? Then you are in the right place. Because this article gives you complete info about the same and if you are confused can grid-tie inverter run on battery, come find out.

What is a Grid Tie Inverter?

Basically, solar inverters can be divided into 3 categories namely on-grid inverters, off-grid inverters, and hybrid inverters. Off-grid inverters are not connected to the utility grid but to the battery, whereas hybrid inverters are connected to both the utility grid and the battery. Today we will discuss on-grid or what is grid tie inverter, and which are best among them with battery backup. So, a grid tie inverter is directly connected to the grid and connects solar panels to the grid as well. It is considered to be the most efficient and cost-effective inverter.

1. Working

Solar panels and grids integrate with each other. Grid-tied inverters serve the purpose of converting Direct Current (DC) generated by solar panels into Alternating Current (AC). The power converter to AC is transferred to the utility grid and then from there to the appliances.

Excess electricity generated and unused during the day is fed into the grid and the owner receives credit for it. They can be used in exchange for power from the grid when there is an insufficient power supply from solar panels. With these credits, your utility bill will be reduced to a large extent.

2. Types of grid-tied inverters

1) Central inverters: A type of larger version of string inverters these central ones are capable of supporting more string of panels. Strings from solar panels are connected together in a combiner box from which DC power is transferred to a central solar inverter. With fewer components required, central inverters do need a combiner box and a pad. These inverters are suitable for large-scale operations.

2) Microinverters: These module-level inverters are installed on each solar panel and perform spot conversion of DC to AC in solar panels themselves. This reduces the requirements for a string inverter. It is also beneficial if one or more panels are shaded, the overall productivity of other panels will not be affected. AC Modules are solar panels with integrated micro inverters, making them cost-effective. Otherwise, the installation cost of micro-inverters is high.

3) Battery-based inverters: These are bidirectional in nature as they include both a battery and an inverter. These inverters can be off/on grid or hybrid depending on their UL rating and design. They are highly efficient with a constant power supply as they manage energy between the grid and array while charging the battery on the side. This process is monitored and regulated by a battery-based inverter.

4) String inverters: Multiple strings of solar panels placed in a string are connected to a string inverter. Each string of solar panels has its own separate string inverter. These inverters serve best where shading is not a problem. The panels are positioned such that they face the same direction. With technological advancement, string inverters are now more capable with great power density in small sizes too.

Can Grid-Tie Inverter Run on Battery?

Yes, the grid inverter can run on a battery. You can install and connect a battery with a grid-tied inverter and convert the whole system to a hybrid inverter system. You can use a battery-based inverter and connect it to the grid. Or you can add a battery to your on-grid inverter and use it as an off-grid inverter.

No, you are still confused, can grid-tie inverter run on battery? The short answer to this question is yes, it can. But before you do such with the best grid tie inverter with battery backup here are a few points to consider.

  • The inverter should be large enough to handle the whole load. This way you can run appliances even in the absence of solar power.
  • It supplies power to the appliances by the time solar power begins generating electricity. Basically, it takes approximately 1 minute or so for solar panels to start generating power. This way, the entire load will be handled by the inverter/generator.
  • More than one generator can be used in sync with solar power systems. But to sync generators with each other, you need a synch panel.
  • To prevent generators and solar systems from being damaged you should isolate generators and solar power plants from the grid.
