For RV owners who want 50 A and a wired remote display without paying Victron or Redarc prices. The short warranty and one-source-at-a-time design hold it back.

Pros
  • 50 A from the alternator or solar, enough to recharge a 100 Ah lithium battery in about 2 hours
  • Comes with a remote display panel, and charge voltages are programmable
  • Accepts 12 V or 24 V vehicle input
  • Draws almost nothing when idle
Cons
  • Uses solar or the alternator, not both at once
  • Fan-cooled, so it makes some noise
  • One-year warranty, the shortest here
  • Temperature sensor is extra
