You can add additional power:

• additional sources like wind or additional panels
• optimize tilt and direction of panels
• clean panels

You can reduce his load:

• Turn off the load during times that it is less critical. This can be programmed into the WEB3 by the customer. The most bang for the buck is to turn off the load during a period of time when panels aren't producing like a few hours during the night.
• Reduce his consumption by lowering resolution on cameras or turning off features that aren't needed.

You can recharge the batteries:

• Use a generator or plug the trailer into an AC source to fully charge the batteries which will give many days before the system goes down again, assuming the weather patterns are still bad. If weather patterns change then the balance is restored.
