The short version
Plus for covered outdoor spots and low idle draw; GC for charging from a generator.
- Chargeverter Plus: The charger will sit in a covered outdoor spot or a cold space.
- Chargeverter GC: It will live next to a generator and you want its generator-oriented design (both models offer dry-contact generator auto-start).
Both Chargeverters turn AC from a generator or the grid into 48 V DC to charge a battery bank, up to about 5 kW. The two models are not interchangeable: the Plus is built for covered outdoor installation, the GC is built around generator use.

Highlighted = the better figure where both datasheets give a number (higher is better, except idle draw). More is not always better: a larger solar input, for example, needs a bigger battery and wiring to use it. Sources: EG4 Chargeverter Plus datasheet · EG4 Chargeverter GC datasheet. Checked September 30, 2026. “Not on datasheet” means the sheet does not list that line, not that the product lacks it.
What the Chargeverter Plus and Chargeverter GC numbers mean
- Output: 5,120 W at 240 VAC for both. At 120 VAC the Plus lists 2,560 W; the GC lists 3,050 W.
- Charge current: 0–100 A at 240 VAC on both; at 120 VAC 0–50 A (Plus) against 0–45 A (GC); at 208 VAC 0–80 A (Plus) against 0–50 A (GC).
- Idle draw: about 4 W on the Plus, about 10 W on the GC.
- Enclosure: IP54 on the Plus, which the maker says allows covered outdoor installation; IP21 on the GC.
- Temperature: the Plus lists -40 to 131 °F; the GC lists 14 to 131 °F.
- Warranty: both list 3 years, and both say it applies only when used indoors.
- Battery: the Plus is specified for 15s or 16s lithium batteries; the GC lists a 48 VDC nominal battery.
Chargeverter Plus or Chargeverter GC: who should pick which
Pick the Chargeverter Plus if…
- The charger will sit in a covered outdoor spot or a cold space.
- You want the lowest idle draw.
- You charge from 208 VAC, where the Plus lists 0–80 A against 0–50 A.
Pick the Chargeverter GC if…
- It will live next to a generator and you want its generator-oriented design (both models offer dry-contact generator auto-start).
- You have more 120 VAC generator power to use, with 3,050 W listed.
- It will be indoors in a space above 14 °F.
EG4 Chargeverter Plus vs GC: questions people ask
Can the Plus really go outside if the warranty says indoors only?
The maker describes the IP54 enclosure as allowing covered outdoor installation, yet both datasheets say the 3-year warranty applies only when used indoors. Read both statements and ask the seller how they apply to your install.
Which is better on a small generator?
At 120 VAC the GC lists 3,050 W of output against 2,560 W for the Plus; at 240 VAC both list 5,120 W.
