FAQs
Are MRCOOL mini-splits compatible with solar?
Yes. When paired with a properly sized inverter and LiFePO4 battery bank, MRCOOL inverter heat pumps perform efficiently in off-grid and hybrid setups.
Should I choose 120V or 230V?
Choose 120V for smaller zones and systems tied to 120V inverters; choose 230V for larger capacities or when your inverter/generator supports 230V output.
