Check my system →The responsible answer
Compatibility first. Clear options second.
Battery storage is electrical infrastructure, not a one-size-fits-all appliance. We review the existing system and the home before recommending equipment or backup capacity.
Questions homeowners ask
Straight answers before you upgrade.
What is a solar battery retrofit?+
It is the addition of battery storage and related electrical equipment to a solar system that is already operating.
Does the original solar installer need to do the work?+
Not necessarily. The retrofit installer must understand the existing equipment, warranties, approvals, permitting, and safe integration requirements.
How long does a retrofit take?+
Timing varies with design, equipment availability, permitting, utility requirements, and inspection scheduling. We outline the expected sequence after the compatibility review.
