Charger types

  • AC Mains Chargers (12V/24V): Bench/workshop charging, maintenance and recovery. Great for cars, 4WDs, boats, ride-ons and backup banks.
  • DC-DC Chargers (Vehicle → House): Safely charges an auxiliary battery from your alternator (and often solar). Ideal for dual-battery touring and caravans.
  • Solar MPPT Controllers: Maximises panel harvest and correctly charges your battery bank in off-grid or hybrid setups.

Quick sizing guide

  • AGM/Gel/Lead-acid: Choose ~10–20% of battery Ah (e.g., 100Ah → 10–20A charger).
  • LiFePO₄: Many systems use ~0.2–0.3C (e.g., 100Ah → 20–30A), but always check your BMS limits.
  • 24V banks: Use a charger rated for 24V (some units auto-detect; others are 12V-only).
Install tips
  • Fuse close to the battery and use the correct cable gauge for charger current.
  • Set the correct charge profile for your battery chemistry in the app/panel.
  • For DC-DC: confirm smart-alternator compatibility and ignition/engine-run wiring where required.
  • For marine/outdoor: consider IP65/IP67 enclosures and corrosion-resistant hardware.
