System Design Guides
Battery energy storage system design guides for matching battery capacity, inverter, solar input, backup loads, protection, and future expansion.
Start With Your Question
Can I add a battery to my existing solar system?
Check the current inverter, solar setup, battery connection, and backup requirements first.
Check Compatibility
Can I use my current inverter with a battery?
Check voltage, communication, charging limits, power rating, and backup support.
Check Compatibility
Which appliances should stay on during an outage?
Start with essential loads and check HVAC, pumps, heaters, motors, and other high-power loads separately.

How much solar do I need to recharge the battery?
Match solar input with daily energy use, battery capacity, charging time, and inverter limits.
Read Guide
Which appliances should stay on during an outage?
Choose essential backup loads first and check HVAC, pumps, heaters, motors, and other high-power loads separately.
Read Guide
Can I add more batteries later?
Check battery expansion limits, inverter capacity, system voltage, communication, and supported battery configuration.
Read Guide
What protection does my battery storage system need?
Check breakers, disconnects, battery protection, inverter protection, and installation requirements before system design.
Read Guide
What should I confirm before buying a commercial BESS?
Check load profile, power demand, backup time, three-phase connection, solar integration, installation site, and future expansion.

Can I use my current inverter with a battery?
Maybe. Check battery support, voltage, communication, charging limits, and backup output first.
Do I need a new inverter when adding a battery?
Not always. A compatible battery-ready or hybrid inverter may already support battery storage.
What should I send before you size my system?
Send the load list, power ratings, daily energy use, backup time, current inverter, solar system, grid type, and installation location.
Which appliances should stay on during an outage?
Start with essential loads. HVAC, pumps, heaters, motors, and other high-power loads need separate checks.
Can I add more batteries later?
Yes, when the battery platform, inverter limits, system voltage, communication, and expansion rules allow it.
How much solar do I need to recharge the battery?
Solar input depends on daily energy use, battery capacity, available sunlight, charging time, and inverter limits.
Can I keep my existing solar panels?
Usually yes, but the inverter, solar input limits, system architecture, and battery connection need to be checked first.
When does the system need engineer confirmation?
Commercial BESS, high-voltage systems, three-phase systems, off-grid projects, and motor loads should be confirmed before equipment selection.
