How this list works

$/A is listed Amazon price ÷ amps of charge current

Every charge controller here is a live Amazon listing. We divide its current buy-box price (coupons ignored) by its rated amps of charge current, then sort from cheapest to most expensive. Out-of-stock listings keep their last seen price and sit at the bottom so a stale price never tops the ranking.

The “Best value” badge only goes to a listing rated 4★ or higher with at least 100 reviews. Switch those filters off to see every listing. $/A only compares fairly within one type, so the list opens on MPPT models.

A listing priced under 30% of the median $/A for its type is marked “Unusually low price” and ranked below the rest. That is usually a wrong price on Amazon or a product that is not what its title claims, so check the listing carefully.

Prices as of Oct 5, 2026 and may have changed since. As an Amazon Associate, Solar Price List earns from qualifying purchases.
