PRODUCT DETAILS
The Go Power! GP-RVC-30-MPPT is a 30-amp MPPT solar charge controller with two battery outputs for 12V and 24V systems, handling up to 600W of solar at 12V (1,200W at 24V). It charges the house bank first and sends surplus to the chassis or starting battery once the house bank reaches absorption, so a motorhome keeps both banks charged from one controller without a separate trickle charger. Up to 98% efficient, lithium-ready, RV-C networked, 5-year warranty and a North American support team (part of Dometic).
Built to the standard RV manufacturers install
Go Power! has designed mobile power since 1996 and is the solar brand fitted at the factory by Jayco, Forest River, Thor and other leading RV builders. The RV-C MPPT series is the current generation of those controllers, with RS485, CANbus and RV-C communication so it reports to PowerTrak™ and other coach displays, accepts panel strings up to 100V open-circuit, and stacks for larger arrays. Part of Dometic.
Two banks, one controller, right priority
BAT1 is the house bank and always gets priority. When it finishes absorption, BAT2 — your chassis or engine battery — receives the surplus so it never goes flat in storage. Single-bank installation? Use BAT1 only; nothing else changes.
MPPT means more charge from the same roof
Maximum power point tracking converts the panels' extra voltage into charge current, harvesting 15–30% more than PWM from the same array, and lets you series-wire panels for lower losses on long cable runs. Select GEL, AGM, Flooded, LiFePO4 or Custom profiles with chemistry-specific absorption, float and recovery voltages.
Monitoring your way
The controller shows PV, BAT1 and BAT2 status on LEDs. Add the GP-RVC-R remote display for a wall readout plus Bluetooth through the Go Power! Connect app — or get both in the 30A MPPT + Remote Kit. Coaches with a PowerTrak™ or other RV-C display see it on the network with no remote.
Which size?
30A covers 400–600W of roof solar on a 12V bank, or up to 1,200W at 24V. For a PowerTrak™-native, UL 1741-listed controller on a 12V coach, see the Dometic 40A dual bank MPPT.

WHAT IT RUNS
Sizing guide for a 12V system: a 30A controller handles about 600W of panels at 12V (1,200W at 24V). Daily harvest assumes 4.5 peak-sun hours at about 70% of nameplate, which is typical for a flat-mounted RV array. MPPT lets you wire panels in series for less voltage drop and better low-light harvest — keep total open-circuit voltage under 100V. Use 8 AWG between controller and battery.
| Array | Nameplate | Typical daily harvest | Wiring |
|---|---|---|---|
| 1 × 100W panel | 100W | ≈ 0.3 kWh/day (≈ 25Ah) | — |
| 2 × 100W panels | 200W | ≈ 0.6 kWh/day (≈ 49Ah) | Series or parallel |
| 3 × 100W panels | 300W | ≈ 0.9 kWh/day (≈ 74Ah) | Series or parallel |
| 4 × 100W panels | 400W | ≈ 1.3 kWh/day (≈ 98Ah) | Series or parallel |
| 2 × 200W panels | 400W | ≈ 1.3 kWh/day (≈ 98Ah) | Series or parallel |

FAQ
How does dual bank charging work?
BAT1 (house bank) is charged first through the full bulk, absorption and float cycle. Once BAT1 reaches absorption, the controller diverts surplus solar to BAT2 — typically the chassis or starting battery — so it stays topped up in storage. BAT1 always keeps priority; if house loads pull it down, BAT2 charging pauses.
Can I use it with just one battery bank?
Yes. Connect your bank to BAT1 and leave BAT2 empty. Everything else — profiles, RV-C, remote — works the same.
How much solar can I connect?
Up to 600W at 12V or 1,200W at 24V, with open-circuit voltage under 100V. That is four to six 100W panels, or three 200W panels, in series or parallel at 12V. Above that, a second controller can be stacked on the same bank.
Does it work with lithium batteries?
Yes. Select the LiFePO4 profile or a Custom profile matched to your battery maker's specification. With Go Power! Advanced Lithium batteries on the RV-C network, state of charge is shared across the system.
Does it have a display or Bluetooth?
The controller has status LEDs for PV, BAT1 and BAT2. Add the GP-RVC-R remote display for a wall readout and Bluetooth in the Go Power! Connect app, or buy the kit. On a coach with a PowerTrak™ or other RV-C display, the controller appears on the network without the remote.
Is this controller UL listed?
No. The GP-RVC-30-MPPT is sold for aftermarket and do-it-yourself installation in the United States only and is not intended for OEM production use; it cannot ship to Canada. If you need UL 1741, see the Dometic SC-DB-MPPT-40-12.
What wire gauge and fuse do I need?
8 AWG from controller to each battery output with a 40A fuse at the battery for BAT1 (a 10A fuse is sufficient for BAT2), and 8–10 AWG from the array depending on run length. Connect batteries before panels when commissioning.
MPPT or PWM — which do I need?
PWM is a switch: it connects the panel to the battery and chops the current, so the panel runs at battery voltage and you lose the difference. MPPT converts the panel's higher voltage into extra charge current, harvesting 15–30% more from the same panels, and lets you wire panels in series. For one or two panels on a simple 12V kit, PWM is cost-effective; for 300W or more, lithium batteries, or long cable runs, MPPT pays for itself.
Is Go Power! the controller installed in my RV from the factory?
Very likely, if your coach is a Jayco, Forest River, Thor or many other brands. Go Power! has supplied RV manufacturers since 1996 and its PWM and MPPT controllers are the ones specified on factory solar-prep and solar-equipped coaches, so this is the like-for-like replacement or upgrade.
What's the warranty?
Five years against defects in materials and workmanship, backed by Go Power!'s North American support team (part of Dometic). Register the product after purchase.
