At a glance

Our top picks

Generator input on a solar controller usually means one thing: an AC charger built into an inverter-charger. Plain solar controllers have no AC input at all, so this guide separates AC-capable hybrid units from solar-only ones and one wind-turbine controller.

This guide favors listings that state AC or mains charging and flags output voltage, since several are 230V products. Solar-only units are included as the solar half of a build that adds a separate charger.

Before you buy

What Matters Before You Choose a Solar Charge Controller With Generator Input

Key buying criteria so you get the right fit the first time.

  1. 01

    A real AC charger

    Only inverter-chargers have an AC input, and plain solar controllers do not. A listing that says hybrid or all-in-one should still name an AC charger or mains charging before you count on generator input. Look for those exact words and an amp figure.

  2. 02

    AC input voltage match

    A US portable generator makes 120V, while some units here are 230V products. Feeding the wrong voltage can damage the charger or simply not work. Confirm the input voltage on the listing and your generator's output.

  3. 03

    AC charge current

    Ampinvt 1200W lets you set AC charge current from 0 to 15A, which is slow for a big bank. A low charge current means long generator run time. Compare the charge amps to your bank size.

  4. 04

    Transfer switching

    An auto-transfer switch moves loads between sources without a manual step. It also prevents feeding your inverter output back into the generator. Look for the switch on the listing.

  5. 05

    Generator power quality

    Some chargers dislike noisy or unstable generator power. An inverter generator with clean output is the safer match. Check the manual for waveform and frequency limits.

FAQ

Before You Bring One Home

Can a solar charge controller take generator power?

No. Only inverter-chargers have an AC input, and plain controllers like Renogy Rover 30A do not.

What mistake do buyers make with a generator-input inverter-charger?

Assuming an MPPT controller can also charge from AC. It cannot, so pair it with a separate charger.

Is an all-in-one worth it?

For a small 12V rig, usually yes, because it saves wiring.

What is the safest way to wire a generator-input inverter-charger?

Wire the generator to the AC input terminals per the manual, with the correct breaker. On a generator-input inverter-charger, double-check polarity at every terminal before powering up and use wire sized for the rated amps.

How should I maintain a generator-input inverter-charger?

On a generator-input inverter-charger, tighten terminals and inspect cable insulation at the start of each season, and keep vents, fans or heat-sink surfaces free of dust. Check terminals and fans each season.
