FAQs
Yes. Its ignition override connection activates the lower input-voltage mode used by smart, variable-voltage alternators.
Yes. Both inputs can charge simultaneously, with solar taking priority when available.
No for an unregulated solar panel connected to the dedicated solar input; the integrated charger provides MPPT regulation. Maximum solar input is 28V DC.
No. Use it in sheltered conditions, keep it out of rain and never clean it with a high-pressure washer.
Yes, within the stated limits: up to 1800W / 150A for 20 minutes, or 1200W / 100A continuously, using correctly rated cabling.
