Okay, so a few questions I need answered to give high quality advice.

What devices is the battery/solar generator intended to power, and how frequently will they be used?

What is the total combined wattage ratings of the devices, and how long do they have to be powered?

What is the brand of battery/solar generator, and what is its capacity?

Are you using the battery/solar generator for everyday use, or for emergency use? If for emergency use, what are the anticipated weather conditions for emergency use? If for emergency use, what is the expected duration of the emergency?

How many days a year are you anticipating the battery and solar panels will be used?

Where will the solar panels be located? Are they permanently fixed in place? How many hours of sunlight does the intended location receive? Have you done a sunlight survey to verify the location receives the maximum amount of sun available?
