#37 Split Phase Inverters for Off-Grid Solar Systems: A Complete Guide

If you are planning an off-grid or hybrid solar system, you have likely come across the term “split phase inverter.” This technology is essential for applications requiring both 120V and 240V power — common in North America, the Caribbean, and many parts of Latin America including Cuba.

What is a Split Phase Inverter?

A split phase inverter converts DC power from solar panels or batteries into AC power with two 120V phases that are 180 degrees out of phase. When combined, these phases deliver 240V, allowing you to power both standard 110V appliances and heavy 220V equipment from a single unit.

Key Benefits for the Cuban Market

Cuba operates on a 110V/60Hz electrical standard, similar to the US. However, many industrial and commercial appliances require 220V. A split phase inverter solves this problem elegantly:

  • Voltage Versatility — Power everything from lighting and electronics (110V) to air conditioners, water pumps, and machinery (220V)
  • Blackout Protection — Cuba experiences scheduled power outages (apagones) lasting 2-8 hours daily. A split phase inverter with battery storage provides seamless backup.
  • Ideal for Tourism — Hotels, casas particulares, and restaurants need reliable power for AC, refrigeration, and kitchen equipment.

Sizing Guide for Cuban Applications

ApplicationInverter SizeKey Loads
