How to choose the right inverter

  1. 1
    Match inverter capacity to your solar array size. A 5kW solar array needs a 5kVA or 5.5kVA inverter.
  2. 2
    If you plan to add batteries later, buy a hybrid inverter from the start (saves ₱15,000+ on future upgrades).
  3. 3
    For roofs with partial shading (common in PH subdivisions), consider microinverters or optimizers.
  4. 4
    Check that the inverter is certified for Philippine net metering (Meralco approved list).
  5. 5
    Choose a brand with local warranty support — not all international brands have service centers in the PH.

Solar inverter FAQs

For most Filipino homes, a hybrid inverter is the best choice. It works with net metering now and allows you to add battery storage later for brownout protection. String inverters are a good budget option for homes with unshaded roofs.
