Frequently Asked Questions
What is the difference between hybrid and off-grid inverters?
Hybrid inverters support battery storage and utility grid interaction, enabling backup power and energy arbitrage. Off-grid models operate independently from the grid, relying solely on solar and batteries for power needs.
Do inverters work without batteries during the day?
Some hybrid models can operate directly from solar input during daytime if voltage requirements are met. However, battery connection ensures stable power and reduces grid dependence effectively.
What does MPPT mean in solar inverters?
MPPT stands for Maximum Power Point Tracking, a technology that optimizes solar panel output to match inverter needs. It increases charging efficiency and energy harvest from your solar array.
Can I connect an inverter to the utility grid?
Only grid-tie or hybrid inverters support grid connection safely. Pure off-grid models cannot feed power back to utilities and must not be connected to grid lines.
How do I choose the right inverter size?
Calculate total wattage of all devices you plan to run simultaneously, then add a safety margin. Consider peak surge needs for appliances with motors like refrigerators or AC units.
What battery types are compatible with these inverters?
Most support AGM, Gel, flooded lead-acid, and lithium variants. Verify specific compatibility in the manual, especially for lithium activation features required by some chemistries.
