If you want to exceed 600W of solar input, you’ll need to set your panels up in
series. There are two ways to do this depending on which Goal Zero solar panels
you have.
If you have Goal Zero solar panels of the same wattage
You can combine up to four Goal Zero solar panels of the same wattage in a series
by connecting them with one 4:1 Series combiner cable (SKU 98715). Plug the
four panels into the cable, then plug the other side of the cable into your Yeti PRO
4000. This configuration allows for up to 1600W of solar input.
If you have a variety of Goal Zero solar panels that have different wattage ratings
If you have an assortment of Goal Zero solar panels of different sizes and you plan
to combine for over 600W of input you will need to use up to three 4:1 Series
Combiner Cables (SKU 98715) and one 3:1 HPP+ Parallel combiner (70030).
• You can connect a maximum of 12 Goal Zero solar panels this way.
• All panels connected to one Series Combiner Cable must have the same
wattage. (For example, you can connect two Nomad 100 panels and two
Boulder 100 panels to one Series Combiner Cable.)
• All Series Combiner Cables must have the same number of panels connected.
(For example, if you have three panels connected to one Series Combiner
Cable, the other Series Combiner Cables must also have three panels
connected.)
Connect your solar panels to the 4:1 Series Combiner Cables, then plug the Series
Combiner Cables into the 3:1 HPP+ Parallel Combiner. Once connected, plug the
3:1 HPP+ Parallel Combiner into your Yeti PRO 4000. This configuration allows for
up to 3000W of solar input.
NOTE: 1800W is the maximum output of most household AC wall outlets. If you’re
powering other loads from this same circuit, you may trip your home breaker and
thus need to reduce your charge speed. To do this, slide the Charge Speed switch
to the “Low” position. This will reduce the charge rate to 400W. Reducing charge
speed will also reduce fan noise. You can also customize your Low speed AC charge
rates in the Goal Zero app.
Input Limit
Switch
Solar Charging
The Yeti PRO 4000 has two DC inputs: The 8mm Low Voltage Input and the HPP+
High Voltage Input.
The Low Voltage DC Input can input a maximum of 275W at 28V. This input is for
smaller, single panel applications.
The HPP+ High Voltage Input can input a maximum of 3000 Watts up to 145V.
If you plan to use Goal Zero portable solar panels and do not plan to exceed 600W
of total solar input, use the 4:1 HPP Parallel Combiner Cable (SKU 98061). This
will allow you to connect any four Goal Zero solar panels together for a maximum
600W of solar input.

Combiner Cables into the 3:1 HPP+ Parallel Combiner. Once connected, plug the
3:1 HPP+ Parallel Combiner into your Yeti PRO 4000. This configuration allows for
up to 3000W of solar input.
NOTE: 1800W is the maximum output of most household AC wall outlets. If you’re

Solar Charging
The Yeti PRO 4000 has two DC inputs: The 8mm Low Voltage Input and the HPP+
High Voltage Input.
The Low Voltage DC Input can input a maximum of 275W at 28V. This input is for
smaller, single panel applications.
The HPP+ High Voltage Input can input a maximum of 3000 Watts up to 145V.
If you plan to use Goal Zero portable solar panels and do not plan to exceed 600W
of total solar input, use the 4:1 HPP Parallel Combiner Cable (SKU 98061). This
will allow you to connect any four Goal Zero solar panels together for a maximum

8mm
Connector
You can also have a licensed vehicle technician connect your Yeti PRO directly to
your alternator for 400W charging.
NOTE: The Yeti has built-in protection that prevents the car battery from
discharging below 11.8 V so it will never over discharge your vehicle’s 12V battery,
even when the vehicle isn’t running.
Automatic Power Switching (APS)
The product will automatically enter the Automatic Power Switching (APS) mode
when you are inputting power into the AC input port and simultaneously outputting
through the AC output. Power will pass directly from the grid or AC power source to
the loads connected to the Yeti and bypass the inverter of the Yeti. If grid power is
interrupted, power will quickly switch to Yeti power.
The Yeti PRO 4000 switches from grid to battery in under 15ms, but it does not
support 0ms switching. Some sensitive loads may be interrupted during the switch
over.
When using your Yeti Pro 4000 in APS mode, note that if the AC output of your Yeti
exceeds your set AC fast charge input limit the input will be disabled and your Yeti
PRO will run off of the internal battery until your AC output drops below your set
charge input limit.
