The lowest unit price may cover a different battery configuration or a smaller delivery scope. Put quotations into a common comparison sheet before deciding which supplier offers the better project fit.
Normalize the technical basis
Record model, nominal and usable energy, voltage, current ratings, enclosure and inverter compatibility. A rounded 20 kWh label is not enough. Keep any missing field visible rather than filling it with an assumption from another model.
Normalize the supplied scope
Compare cables, mounting hardware, manuals, packing and spare parts. Check whether freight, installation and local protection are excluded. A quotation with accessories included can be materially different from a bare-battery price.
Compare evidence and service
List which documents are available before ordering, how sample acceptance is defined and what the warranty actually covers. Lead time, repair route and responsibility for transport can affect the practical cost of a supply arrangement.
Details to confirm
- Same electrical and mechanical basis
- Same accessories and packaging
- Same delivery term and named place
- Written warranty and document availability
Should I compare price per nominal kWh?
It is one useful screening number, but it should be accompanied by usable energy, power, scope and service terms.
Product and project review
See the related Graspmart battery specifications and compare the available capacities. Use the reference data to shortlist a platform, then confirm the exact production model, accessories and operating limits in the quotation.
Send the inverter model, destination, quantity and the requirements listed above through the project enquiry form. Include existing equipment details when the battery is being added to an installed system.
