A solar generator is primarily a means for emergency power backup. It is designed with a sole purpose to supply solar energy in an emergency situation or camping. Hence, there is less significance in the aesthetic portion of solar generators. Whatever design it has, whether it is of a briefcase, cart or drolly, the basic thing a solar generator should have is the facility to effortlessly drag it on smooth and tough terrains alike.
On the basis of this portability factor, both the solar generators are good and are highly recommended for outdoor life. They are designed in style of moving-friendly suitcases with sturdy collapsible handles and wheels to let you tug them comfortably.
But when it comes to the physical form, GOAL ZERO YETI 1250 SOLAR GENERATOR KIT has a pretty colorful and rather chic look, thanks to its blend of white, black and green colors. The BePreparedSolar’s generator also keeps a cube-like form, but it seems rather run-of-the-mill and unexceptional, and it is heavier than the Goal Zero competitor.
Though priced equally, the bundle of Yeti 1250 doesn’t contain solar panels, while the BePreparedSolar generator does. It costs a little bit of extra for a Yeti user to buy separate solar panels to attach with the system. Whatever it is, let us check out the output power and other tech specs of the devices. As its name tells, Yeti 1250 promises continuous output of 1250 watts and it goes up 1500 watts during peak hours.
Compared to this, BePreparedSolar generator in discussion offers a whopping 2500 watts of continuous power, while in peak hours it is even capable to produce as much as 5000 watts. This difference is also visible in the battery capacity of the machines. The former packs a 100Ah unit, while the latter has a 200Ah battery.
When it comes to the capacity of solar panels, the BePreparedSolar model bundles up a pair of 100W solar panels. As for Yeti 1250, you will need to buy separate panels, which are available in many varieties from Goal Zero itself. Ultimately, you get double the power from the entire Be Prepared Solar generator – its inverter, solar panels and battery are twice powerful compared to its Yeti rival.
THERE ARE 3 WAYS TO CHARGE YOUR GOAL ZERO YETI 1250:
The Sun
The Goal Zero Yeti 1250 can be charged by connecting a compatible solar panel (see the chart below for solar compatibility or use our Solar Charging Calculator).
Wall
The Goal Zero Yeti 1250 can be recharged from a regular wall outlet in about 18 hours. You can charge your Yeti with solar panels, and a wall charger at the same time.
Car
Although not the most ideal recharge time, the Goal Zero Yeti 1250 can also be charged by plugging into your car 12V adapter in about 44 hours. You will need to purchase an 8.0mm to 12V Charger.
Full-size refrigerator runtimes from the Yeti 1250 are dependent on several factors, including the year, make and model of your refrigerator, as well as its volume, fullness and usage. We actively test a variety of refrigerators to determine an average runtime. For the longest runtimes and to optimize performance, we suggest limiting the opening and closing of refrigerator doors when powering from the Yeti 1250.
