Battery capacity alone does not define whether a system will work. These four checks reduce compatibility and commissioning risk.
How compatibility is verified- LoadDaily energy, peak power, starting loads and backup circuits.
- InverterExact model, phase, firmware, protocol and current limits.
- InstallationIndoor or outdoor location, temperature, space and expansion plan.
- MarketRequired documents, certification scope, language and delivery terms.
GRASPMART CARE
Support continues after the battery ships.
Selection
Match energy, power and inverter requirements before ordering.
Commissioning
Provide the applicable manual, wiring and configuration information.
Diagnostics
Use alarms, logs and measurements to isolate system faults.
Warranty path
Coordinate evidence, approved parts and RMA decisions by configuration.
MANUFACTURING VISIBILITY
Battery assembly and inspection
Assembly-stage units expose the modules, wiring and control hardware that are hidden after final enclosure. Buyers can specify the inspection records and packing evidence required for their order.
How production and quality are coordinatedWHAT YOU RECEIVE

About Graspmart
Graspmart works with manufacturing partners to coordinate product selection, technical documents, sampling, delivery and after-sales enquiries for distributors and solar installers. Our focus is low-voltage home storage, with the exact battery configuration and order scope agreed before supply.
Company, manufacturing coordination and order process
Compare capacity, power and included equipment
Energy and runtime
Nominal kWh is only the starting point. Compare usable SOC, reserve, conversion losses and the load you want to support.
View the capacity comparisonPower and compatibility
Check inverter voltage, current and protocol. A 20 kWh battery does not automatically deliver 20 kW.
Check inverter requirementsDocuments and support
Review the exact model, document revision, warranty issuer, exclusions and support route alongside price.
Review Graspmart CareWhat happens after you enquire?
- Share country, inverter model, required capacity and quantity.
- Resolve missing compatibility and installation information.
- Review a quotation identifying the model, included equipment, delivery terms and warranty scope.
