The Go Power! 190 Watt OBSIDIAN Series 9 Solar Panel Expansion Kit Adds a Matching Low-Profile Panel and About 57Ah a Day of Summer Charging
The Go Power! 190 Watt OBSIDIAN Series 9 Solar Panel Expansion Kit is a 190W monocrystalline panel with pre-installed solar connectors. It adds a second panel to an OBSIDIAN kit, or to any MPPT solar system with spare controller capacity, and it matches the KIT1056 panel so your array stays even and low on the roof.
Go Power estimates the panel adds about 57Ah a day into a 12V battery on a sunny spring or summer day and about 23Ah a day in fall and winter, on top of what your existing array produces. It has no controller or mounts, so it works with the equipment you already have.
Go Power! 190 Watt OBSIDIAN Series 9 Solar Panel Expansion Kit Features
A 190W Panel in a 0.6-Inch Frame
The panel measures 55.8 x 28 x 0.6 inches and weighs 23.8 pounds. It's rated at 190W, with 18.2V and 10.3A at maximum power, a 21.5V open circuit voltage, a 10.8A short circuit current and a 300V maximum system voltage.
Nine Bus Bar Cells and Bypass Diodes
The monocrystalline cells use nine bus bars under tempered anti-reflective glass, and the low-profile junction box holds bypass diodes for shade resistance. The anodized aluminum OBSIDIAN frame has the same 0.6-inch height as the KIT1056 panel.
Series or Parallel Wiring
With an MPPT controller, you can wire two OBSIDIAN panels in series, for 43V open circuit, to cut cable losses on long runs, or in parallel to better tolerate partial shade. With a PWM controller, wire in parallel only. The pre-installed connectors make either connection without tools.
Works Beyond OBSIDIAN Systems
Go Power describes it as a standard 12V-nominal panel. Any controller with at least 10A of spare capacity can accept it, and with a PWM controller you wire it in parallel with panels of similar voltage.
Real-World Applications
Growing a KIT1056. Add one or two panels to the 190W OBSIDIAN kit's 30A controller, up to 570W in total.
12V fridge camping. Go Power puts a 12V compressor fridge at about 50Ah a day, and this panel's summer estimate alone covers it.
Other MPPT systems. Add 190W to an existing MPPT setup that has room for about 10A more current.
Practical Comparison
190W OBSIDIAN Expansion Versus the 200W Overlander Expansion
Go Power estimates the 200W Overlander Expansion at about 60Ah a day in summer and 24Ah in winter, and the 190W OBSIDIAN Expansion at about 57Ah and 23Ah. Go Power positions the Overlander panel for factory Go Power! systems and this panel for OBSIDIAN and MPPT systems, where it keeps the low 0.6-inch profile.
Expansion Kit Versus the Complete KIT1056
The KIT1056 pairs the same 190W panel with a 30A PowerTrak MPPT controller as a complete starting kit. Choose the KIT1057 when you already have a controller with room for another panel.
Buyer Guidance
Check Controller Capacity
On a KIT1056, the 30A SC-DB-MPPT-30-12 is rated for 600W of solar at 12V, and Go Power says it takes the kit panel plus up to two KIT1057 panels, for 570W. For more, Go Power suggests a second SC-DB-MPPT controller or the 40A SC-DB-MPPT-40-12. Plan mounting hardware separately, since the panel ships without mounts.
This May Be A Good Fit If
- You own a KIT1056 and want more solar
- Your MPPT controller has at least 10A to spare
- You want added panels to keep a low profile
- You run a 12V battery bank
Common Questions
How Many Can I Add to the KIT1056?
Up to two. The KIT1056's 30A controller is rated for 600W of solar at 12V, and the kit panel plus two KIT1057 panels comes to 570W.
Will It Work With a Non-OBSIDIAN System?
Yes. It's a standard 12V-nominal panel with pre-installed solar connectors. Any controller with 10A or more of spare capacity can accept it. With a PWM controller, wire it in parallel with panels of similar voltage.
Does It Include a Controller or Mounts?
No. It includes the panel with pre-installed connectors. Use your existing controller and add mounting hardware separately.
What Warranty Does It Carry?
Go Power gives the panel a 25-year limited power output warranty.
