Solar Inverters
We carry a full lineup of pure sine wave inverters and inverter/chargers — 12V, 24V, and 48V — for RVs, off-grid cabins, and whole-home backup systems.
High-Frequency vs. Low-Frequency: What's the Difference?
Every inverter below is tagged High-Freq or Low-Freq — that's the core design of the unit, not just a spec number, and it affects what it's actually good at.
High-Frequency
Uses a compact switching transformer instead of a big 60Hz one — the Renogy and Magnum units below.
- ✓ Smaller, lighter, easier to mount
- ✓ Higher efficiency, less idle power draw
- ✓ Lower cost
- ✗ Shorter-lived electronics than a transformer
- ✗ Less surge headroom for hard-starting motors
Low-Frequency
Built around a large 50/60Hz transformer — every Outback, the Sunny Island, and the Schneider/Xantrex below.
- ✓ Much higher surge capacity — often 3x rated power
- ✓ Better for well pumps, compressors, and other motor/inductive loads
- ✓ Transformer typically outlasts the electronics of an HF unit
- ✗ Heavier and bulkier
- ✗ Lower efficiency, higher idle draw
Rule of thumb: if your loads are mostly electronics, lights, and small appliances, a high-frequency unit is lighter and cheaper for the job. If you're running well pumps, air compressors, power tools, or anything else with a motor that draws a hard surge on startup, a low-frequency inverter is the more dependable choice.
