Overview AC Coupling: The Solar PV feeds a standard grid-tied inverter which then feeds power into the output of a battery based hybrid inverter. The output of the battery inverter tricks the grid-tied inverter to power up and feed into the system when the grid fails. DC Coupling: The Solar PV feeds dedicated charge controllers,… Continue Reading DC/AC Coupled Design Practices for Battery Systems

There are two battery types commonly used with solar: lead-acid and lithium-ion. Each type has its pros and cons. The standard battery for solar applications is lead-acid, however, with the advent of low cost wall mounted lithium packs, we’re seeing more of a mix of both chemistries. Lead acid has a lower cost per kWh,… Continue Reading Why We Chose The Batteries That We Use
