3 Phase Solar Inverter: An In-depth Guide

Explore the advantages of using a 3 phase solar inverter in your solar energy system, understand potential setups for commercial applications, and get expert insights on cost-effective solutions.

I was asked to assist in the deployment of a 100 kW 3 phase commercial PV system. Budget constraints are a key consideration. We found the inverters to be quite costly and are seeking alternative options.

1. Is it feasible to utilize a single-phase PV system to backfeed the 3 phase main panel?
2. Can three single-phase PV inverters be configured to mimic a 3 phase inverter? A suggestion was made that this might be possible.

Any additional suggestions would be appreciated.

When considering the implementation of a 3 phase solar inverter, a few aspects must be kept in mind to ensure effective energy management and cost-efficiency.

Possible Alternatives to 3 Phase Inverters

1. If you choose to employ a single-phase system, it requires a switch scheme to isolate 1 phase loads from the 3 phase utility source. Co-existence is not possible, and the cost-saving might be marginal after all the requirements are met.
2. Using three separate single-phase inverters in a coordinated 3 phase setup is another option. However, these inverters need to be specifically designed to work together, which could ultimately be more expensive than a dedicated 3 phase inverter.

Before embarking on this path, ensure the requirements for 3 phase power are thoroughly investigated and justified, as the need for 3 phase power entails specific costs.

Grid-Connected vs. Off-Line Inverters

Inverters come primarily in two types: Grid Connect and Off-Line. If the PV system must operate independently from the grid, an Off-Line inverter and a transfer switch are necessary. On the other hand, if the goal is to feed excess power back into the utility grid, a Grid Connected inverter is required, and it tends to be more expensive.

Understanding the distinctions and specific needs will help you choose the right inverter for your solar PV system.
