The short answer
The Enphase IQ EV Charger 2 (48 A) is the best EV charger for a solar home: it adjusts in 1 A increments specifically to track surplus solar, carries a NEMA 4 enclosure and a 5-year warranty, and is the natural choice if the roof is already Enphase. The Emporia Pro is the pick on a mixed-brand roof, because its included whole-home monitor measures net draw regardless of who made the inverters. Both beat a bigger charger that can only step in coarse jumps.

| 1 |  Enphase IQ EV Charger 2 (48 A)The charger to buy if you have solar: it adjusts in 1 A increments to absorb whatever the array is exporting, and it carries a 5-year warranty, the longest here. | A house with rooftop solar | 8.7 | $1,011.60View on Amazon $1,124.00 list · 10% off |
| 2 |  Emporia Pro Level 2 EV ChargerThe best-balanced 48 A charger for a typical US house: full 11.5 kW hardwired, and the only unit at this price that ships with a whole-home energy monitor so its load management is reading your actual panel rather than guessing. | Most households, and anyone with a tight panel | 9.0 | |
| 3 |  ChargePoint Home Flex (hardwired, 50 A)The most adjustable charger on this page: output steps through 16, 24, 32, 40, 48 and 50 A in the app, so one unit fits almost any panel and can be turned up later if you upgrade the service. | A house whose panel headroom is uncertain | 8.9 | |

Why granularity beats amperage on a solar house
A 7 kW array on a mixed October day does not produce 7 kW. It produces 2 kW, then 4.5, then 1.8 as cloud passes. A charger that can only run at 16, 24, 32 or 40 A has four settings to cover that, and any one of them is either wasting export or pulling from the grid. A charger that moves in 1 A steps has thirty-five.
240 V x 1 A = 240 W; 240 W x 4 h
about 1 kWh a session
Arithmetic at 240 V single phase. The point is the tracking error, not the single step: a coarse charger spends most of a variable day several amps away from the available surplus in one direction or the other.
This is also why the honest version of "solar charging" is surplus charging. Unless you have a battery, charging after dark is grid charging whatever the annual net figures say. Our solar EV charging guide works through the economics, and time-of-use rates covers the tariff side.
| Charger | Output steps | Max output | Warranty |
|---|---|---|---|
| Enphase IQ EV Charger 2 (48 A) | 1 A increments, solar-tracking | 48 A / 11.5 kW | 5 years |
| Emporia Pro | Measured whole-home load management | 48 A / 11.5 kW | 3 years |
| ChargePoint Home Flex | 16, 24, 32, 40, 48, 50 A in the app | 50 A / 12 kW | Manufacturer warranty |
| Enphase IQ EV Charger 2 (40 A, plug-in) | 1 A increments, solar-tracking | 40 A / 9.6 kW | 5 years |
The picks
1. Enphase IQ EV Charger 2 (48 A) — built for the job
A house with rooftop solar
Enphase IQ EV Charger 2 (48 A)
48 A / 11.5 kW hardwired, NEMA 4, UL certified, 5-year warranty, and 1 A output steps intended to follow surplus solar.
Enphase publishes solar tracking as a design intent rather than an add-on, and the 5-year warranty is the longest among the units we cover. The strongest case for it is a roof already running Enphase microinverters, where the charger and the production data live in the same system. On a 60 A two-pole breaker with 6 AWG copper — see the wire size guide. Our full review has the rest.
2. Emporia Pro — the brand-agnostic option
Most households, and anyone with a tight panel
Emporia Pro Level 2 EV Charger
48 A / 11.5 kW, 25 ft cable, NEMA 4, and a whole-home energy monitor in the box that measures net import regardless of inverter brand.
#ad Price as of October 28, 2026. How we make money
Measuring at the panel rather than at the inverter is the practical advantage here: it works on a SolarEdge roof, a string-inverter roof or a roof with two generations of hardware on it. It also gives you the per-circuit data that makes a load calculation honest.
3 and 4. Coarser control, lower cost
If 1 A steps are more than you need
The ChargePoint Home Flex steps through six amperage settings in the app, which is enough if your surplus is predictable or you charge mostly at night on a cheap tariff. The 40 A plug-in Enphase keeps the 1 A tracking for a garage that already has a 14-50.
A house whose panel headroom is uncertain
ChargePoint Home Flex (hardwired, 50 A)
The most adjustable charger on this page: output steps through 16, 24, 32, 40, 48 and 50 A in the app, so one unit fits almost any panel and can be turned up later if you upgrade the service.

Solar plus an existing 14-50 outlet
Enphase IQ EV Charger 2 (40 A, NEMA 14-50)
The plug-in Enphase: the same 1 A solar tracking on a NEMA 14-50 cord, which gets a solar household charging on surplus without pulling a new circuit.
We earn commission on qualifying purchases at no cost to you. Affiliate disclosure.
The plug-in Enphase is the easier retrofit of the two, and a GFCI breaker is required on the receptacle circuit under NEC 625.54. The two units at the top of this page are set against each other directly in Enphase IQ EV Charger 2 vs Emporia Pro.
What we deliberately left out
- Bidirectional and V2H hardware. A different purchase with a different approval path — our bidirectional charging guide covers it honestly.
- Chargers whose "solar mode" is a scheduling timer. A timer that charges at noon is not surplus tracking, and we do not rank it as if it were.
- Any claimed payback period. Export rates, array size and driving patterns decide that, and a number we invented would be worthless.
How we picked
Every unit here is currently purchasable, carries a real UL or ETL certification to the relevant standard, and comes from a brand with an identifiable North American support path. We verified each one's published specifications against the manufacturer's own documentation on the date shown at the top of this page. We verify specifications; we do not bench-test hardware, and our methodology says so in plain terms. Ranking order is fit for the stated use case first, then price, then warranty and support — commission rate plays no part in it. On this page the ranking metric is published output granularity and where the measurement is taken — at the inverter or at the panel — rather than headline amperage.
