Summary

300 W in A Briefcase, its specs disagree

What it is: four 75 W framed panels hinged into a 300 W briefcase with self-deploying kickstands, for larger Yeti stations
The trade-off: big output with no glass to break, but below-typical module efficiency and no output guarantee
Conflict: the user guide and product page give different sizes, weights and front-sheet materials
Not checked: temperature coefficient and bypass diodes; Goal Zero publishes neither
Look elsewhere for: an MC4 lead or a panel made for permanent mounting

Strengths

Big output from one folding briefcase
Kickstands fold out as it opens
Polymer frontwith no glass to crack
Sealed junction box

Drawbacks

Module efficiency below the typical folding panel
No power-output warranty
Station plug onlywith no MC4 lead
Goal Zero's own pages disagree on sizeweight and front sheet
Not made for permanent mounting

Description

The Goal Zero Ranger 300 Briefcase (SKU 32450) is a folding portable solar panel of four 75 W monocrystalline panels in thin aluminum frames, hinged into a briefcase with built-in handles, magnetized corners and a kickstand that folds out as the panel opens.

Goal Zero's user guide gives an ETFE polymer front shield and an IP65 junction box; the product page calls the shield PET polymer. It is rated 300 W, 19.3 V at maximum power and 23 V open-circuit, and its fixed 6 ft 12 AWG High Power Port cable delivers 14 to 23 V at up to 21 A (300 W).

The user guide gives 30.6 x 105.9 x 0.9 in (77.7 x 269.0 x 2.3 cm) unfolded, 30.6 x 26.3 x 3.8 in folded and 39 lb (17.7 kg). The product page gives 31.26 x 94.29 x 0.9 in unfolded, 31.26 x 23.39 x 3.8 in folded and 37.71 lb (17.12 kg).

Goal Zero lists charge times from 4 to 8 hours for a Yeti 1000X to 24 to 48 hours for a Yeti 6000X, and says it is not designed for permanent roof mounting. The box holds the panel with its cord and kickstand and a canvas carrying bag. Goal Zero's warranty policy, the product page and the user guide give 2 years.

It sells at $799.95 on goalzero.com. The (2) Ranger 300 BC Solar Panel Bundle, two panels with a 4x High Power Port combiner and a 30 ft extension cable, sells at $1,694.80.
