Payback (years) = (Total CapEx − Subsidies) ÷ Annual Net Savings
| Input | Illustrative Value | Note |
|---|---|---|
| Total CapEx | USD 4,500 | Illustrative placeholder — actual CapEx is OEM-specific |
| Subsidy / grant | USD 0 | METI/MAFF subsidy eligibility must be confirmed |
| Annual savings — outage-loss avoidance | USD 600/year | Avoided revenue loss during grid outages |
| Annual savings — tariff arbitrage (if paired with PV) | USD 450/year | Optional, only if PV is installed |
| Annual OpEx | USD 150/year | Service + spare-parts reserve |
Annual Net Savings = (USD 600 + USD 450) − USD 150 = USD 900/year
Payback = USD 4,500 ÷ USD 900 = 5.0 years (illustrative)
| CapEx ↓ / Annual Net Savings → | USD 600/yr | USD 900/yr | USD 1,200/yr | USD 1,500/yr |
|---|---|---|---|---|
| USD 3,500 | 5.8 yr | 3.9 yr | 2.9 yr | 2.3 yr |

Download the OEM datasheet for LFP-Wall-15kWh (cell chemistry, nominal energy, dimensions, weight, BMS parameters, cycle life, certifications). The download link is delivered by email after the RFQ form above is submitted.
Request Spec / Datasheet DownloadBackup power for lighting, POS, hair dryers and HVAC controls during grid outages. 15 kWh covers typical salon loads for several hours; exact runtime depends on the connected load profile.
Japan typically requires UN 38.3 transport testing for lithium batteries and PSE round (electrical appliance safety) for certain categories. Confirm the exact applicable scheme with METI and a Registered Conformity Assessment Body before ordering.
Yes, Tradvolt can quote DDP Yokohama, Tokyo or Osaka once the HS code, unit quantity, Incoterm and target certification are confirmed in the RFQ form.
Warranty terms are OEM-specific (typical range: 10 years or a stated cycle count, e.g. 6,000 cycles at 80% DoD). Request the OEM datasheet through the Spec/Datasheet download CTA.
Payback in this page is computed as: (CapEx − Subsidies) ÷ Annual Savings. Savings sources vary (outage-loss avoidance, optional PV tariff arbitrage). All figures are illustrative and not a commercial quote.
Lead time depends on the OEM production schedule, certification scope and shipping window. Submit the RFQ form for a current factory-acceptance date.
