EB 70 paired with non bluetti solar panels

My colleague just started using the Bluetti EB70 with the 200W bluetti solar panels. He lives in a high desert situation with extreme winds, sand storms, and is concerned about damaging the panels, so is considering pairing with less expensive, but less fragile solar panels. What considerations are necessary to connect non Bluetti panels, how many watts and other specs?

Limit your voltage to a maximum of 29 volts. This will limit you to a single large panel or two smaller panels connected in parallel.

For all practical purposes if you can find a single panel of 300 watts or less that does not exceed 29 volts then it would be ideal. The incoming 8 amp limit is the limiting factor in being able to locate a panel that can supply 200 watts (limit of the EB70) of incoming solar charging. If you output 200 watts, most panel combinations will exceed the 8 amp limit if they are capable outputting 200 watts.

If you connect two smaller panels (say 100 to 120 watts each) you will also exceed the 8 amp limit and you will not get close to the 200 watt incoming charge spec. In reality you will most likely be able to achieve a 150 to 160 max charge rate in perfect sun and panel alignment no matter the panel combination.

A single panel such as the bouge RV 180 watt solid panel would work fairly well as long as you are willing to accept that you are not going to see a 200 watt incoming wattage for charge rate. This would be very similar to the existing 200 watt panel you now have but with a non portable panel of somewhat lower output “potential”


Thanks, Scoot appreciate the details in your answer. We will evaluate our choices and this info is very valuable.
