The quick answer
Select an energy storage inverter with the battery and installation design, not as a standalone purchase. Check the exact model’s battery compatibility, backup capability, supply phase and suitability for an existing or new solar system.
Are you adding storage to an existing system?
Tell the installer whether you already have solar panels, an inverter or batteries. Provide model numbers, photographs and available commissioning documents. Equipment that works in one arrangement may not fit a different storage design.
For an existing Bangalore installation, ask whether the proposal replaces equipment or adds a separate system. Get a clear diagram of the intended arrangement and a written explanation of which existing components will remain in use.
Check the selected Solis model and approved battery pairing
Pai Power Solutions lists Solis energy storage inverter products. The exact model suffix matters: verify its datasheet, battery voltage range and supported communication requirements. A family name or a product photograph is not enough to establish compatibility.
Solis publishes battery matching guidance for specific inverter models. Ask the supplier for the current list applicable to the exact model being quoted. A historical compatibility document for another model must not be treated as approval for your proposed pairing.
- Existing equipment model numbers
- Exact inverter model and supply phase
- Current battery matching documentation
- Backup-output limits and included commissioning
Plan the installation and customer handover
Confirm where the inverter and battery will be installed, how they will be protected and what access is needed for service. Request an itemised scope covering electrical work, settings and monitoring rather than comparing only the inverter price.
At handover, ask for operating instructions, monitoring access, warranty documents and a service contact. Ask the installer to explain the normal display, reserve settings and what to do if an alarm appears. Choose equipment against your use case rather than assuming storage guarantees a particular bill saving or runtime.
Common questions
Can storage be added to my existing rooftop solar system?
It may be possible, but the existing equipment and proposed arrangement must be assessed. Share model numbers and installation details before selecting an inverter or battery.
Is every Solis battery compatibility list valid for every inverter?
No. Use current guidance for the exact inverter model and battery model. Similar product names do not establish compatibility.
