The Go Power! 190 Watt OBSIDIAN Series 9 RV Solar Kit combines one 190W monocrystalline panel with the Dometic SC-DB-MPPT-30-12, a 30A dual bank MPPT charge controller that communicates over RV-C and works with the PowerTrak system. Go Power estimates the kit puts about 57Ah a day into a 12V battery on a sunny spring or summer day, and about 23Ah a day in fall and winter.
It's made for RVs, vans and overland rigs that need daily solar charging from a single roof panel, and it fits coaches that already run PowerTrak components. Go Power gives the panel a 25-year power output warranty and the controller a 5-year warranty.
The panel measures 55.8 x 28 x 0.6 inches and weighs 23.8 pounds. Its anodized aluminum OBSIDIAN frame is aerodynamic and sits close to the roof. Tempered anti-reflective glass covers monocrystalline cells rated at 190W, with 18.2V and 10.3A at maximum power and a 21.5V open circuit voltage.
Bus bars are the thin conductors that collect current from each cell. These cells use nine, and Go Power says the shorter current path cuts resistance losses. The low-profile junction box holds bypass diodes that limit the loss of output when part of the panel is shaded.
Unlike a PWM controller, which runs the panel close to battery voltage, this MPPT controller tracks the panel's maximum power point as light and temperature change. The manual rates it at up to 98% conversion efficiency and up to 99.9% tracking efficiency. It charges at up to 30A in total and accepts up to 600W of solar at 12V (1,200W at 24V), with a 96V open circuit limit. A second battery output trickle charges a starter or auxiliary battery at up to 2.5A, so you can maintain the starter battery while the RV is parked.
Choose gel, AGM, flooded, LiFePO4 or a custom profile. The controller works with LiFePO4 batteries that have a built-in battery management system. It charges in bulk, absorption and float stages, with optional equalization, and an external temperature sensor port adds temperature compensation for lead acid batteries.
The controller reports solar power, battery voltage, charge state, daily amp-hours and fault codes over RV-C. Add a PowerTrak Display to see that data and change settings, then pair the display with the Go Power! Connect app to check your system from a phone. Up to eight controllers can work together on one system.
The controller protects against battery reverse polarity, over temperature, internal overvoltage, PV overcurrent and reverse current from the battery to the panel. Green, yellow and red LEDs show charging, warning and fault status. Go Power describes the controller as UL Listed, with UL 1741 among its standards.
PowerTrak coaches. Add solar charging that shows up on the PowerTrak Display beside your other PowerTrak devices.
Weekend trips. Go Power estimates LED lights, a vent fan, a water pump and phone and laptop charging at about 25Ah a day, which this kit covers on a sunny summer day.
12V fridge camping. Go Power puts a 12V compressor fridge at about 50Ah a day, which the kit covers in summer. With the weekend basics added, the draw is about 75Ah a day and the kit covers about 76% of it in summer.
Both kits use the same 30A PowerTrak MPPT controller. Go Power estimates the 190W kit at about 57Ah a day in summer and 23Ah in winter, compared with about 64Ah and 26Ah for the 215W kit. The 190W kit expands with the KIT1057 panel, and the 215W kit with the KIT1053.
Go Power's 200W Overlander Kit uses a 30A PWM controller with Bluetooth and is estimated at about 60Ah a day in summer and 24Ah in winter. The OBSIDIAN kit uses an MPPT controller with RV-C reporting instead, along with the low-profile panel.
Mount the controller indoors, vertically on a non-flammable surface with the terminals facing down, as close to the battery as you can and with 6 inches of clearance above and below. The manual calls for 10 AWG wire and a 30A fuse to the main battery, and 16 AWG wire and a 10A fuse to the second battery. Keep the main battery run within 10 feet, the second battery run within 20 feet and the run from the solar array to the battery within 25 feet. Fuses and breakers are not supplied with the controller.
The controller ships set to the AGM profile, and its manual names the PowerTrak Display, sold separately, as the remote for changing settings. Plan on one if you run lithium. Go Power's rule of thumb is about 100W of panel per 100Ah of battery, and the 30A controller has room for up to two KIT1057 expansion panels, for 570W in total.
Yes. The controller has a LiFePO4 profile for lithium iron phosphate batteries with a built-in battery management system, plus gel, AGM, flooded and custom profiles. Because the default is AGM, select the lithium profile with a PowerTrak Display.
The controller charges on its own and shows its status on three LEDs. To view data or change settings, you need a PowerTrak Display, sold separately.
Yes. Go Power rates the 30A controller for up to two KIT1057 190W expansion panels, for 570W in total. For a bigger array, Go Power suggests a second SC-DB-MPPT controller on the same PowerTrak network or the 40A SC-DB-MPPT-40-12.
Go Power gives the panel a 25-year limited power output warranty and the controller a 5-year warranty.
The Go Power! 190 Watt OBSIDIAN Series 9 RV Solar Kit gives your 12V system a low-profile 190W panel and a 30A dual bank MPPT controller that reports over RV-C, with room for up to two matching expansion panels later. If you'd like help planning cable runs, fuses or a PowerTrak Display for your coach, the Outbound Power team is happy to help.
