Pro Tips – Some Things to Consider When Buying an Off-grid System:

• Oversize your solar panels: They are cheap to add, and help meet summer and winter loads more easily.
• Right-size your batteries: Avoid undersizing to protect lifespan and reduce reliance on generators – insist on expandable battery storage.
• Future-proof your system: You can easily add more batteries later as your energy use grows. Remote programming available.
• Plan for future demand: Consider upsizing your inverter now if you expect to add a pool, EV charger, or large aircon later.
