On-grid PV without batteries is by far the most popular and economic solar installation because of its lower initial cost and maintenance-free operation. Integrated inverters convert the DC electric energy the panels generate into the AC current that your home uses. Its energy feeds directly to the home’s loads with any excess going up to the grid. However, it will not operate during a grid outage (this is a safety feature).
On-grid PV with batteries, a hybrid system, marries the solar PV system described above with batteries (energy storage system or ESS). The ESS helps maximize solar production that may have been more than what was needed in the home during the day — storing the energy for use during dark hours, rather than exporting it to the grid. It can also provide back-up power to select circuits during utility outages.
Direct PV is solar panels connected to DC-only powered devices and appliances. Without an ESS – batteries, it will only operate when the sun shines and at varying levels of current. connected to DC-only powered devices and appliances. Without an energy storage system (or ‘ESS’ – batteries, mainly) in between the two, it will only operate when the sun shines and at varying levels of current.
Off-grid PV with batteries is used primarily when access to grid-supplied energy is impractical and/or too expensive. The solar energy system generation maintains the ESS, both having been sized appropriately to the number of loads and their run times.
