I am a novis to all of this, I bought a Eco worthy solar pump kit las year with a 120 whatt solar pannel and a 10Wh battery . I is only used once a year a a camp foe showers. The pump will run for a littlo over a hr. on battery alone. is there an option for more battery to be connected to the pannel and kit like the 20wh portable rechargeable battery?
