LVTOPSUN LVTS-128100-S4 12.8V 100Ah Battery

The selling price on this page is ৳26,000. The regular price is ৳30,000. That price is for the battery. It does not include an inverter, solar panels, cables, protection gear, or installation.

No. LVTS-128100-S4 stores 1.28 kWh. Kilowatt-hours are stored energy. Kilowatts are power. The charge and discharge lines below are the power limits, not the stored energy.

LiFePO4 (lithium iron phosphate), as printed for this LVTOPSUN model. That does not describe every lithium battery.

Nominal voltage is 12.8 V. The 12.8 V catalog row prints bulk charge 14 V, float 13.8 V, low voltage 12.8 V, and cutoff 11.6 V.

Charge current 50 A. Discharge current 100 A. Short-circuit current is printed as about 1,000 A. A maximum on a datasheet is not a promise that every inverter will use it.

The sales image prints 1.28 kg beside a weight icon. That figure tracks the stored energy, not a measured mass. The reviewed sheet lists 9.85 kg. This page uses the sheet.

Block battery. The reviewed catalog lists LVTS-128100 / LVTS-128100-E. This SOLAR24 listing uses the S4 model code. Size on the reviewed sheet: 260 × 168 × 210 mm. Weight: 9.85 kg.

Ingress protection on the reviewed sheet is IP54. Match the manual for sun, rain, and ventilation. An IP rating is not permission to leave the battery in standing water.

Working temperature −20°C to 60°C on the catalog page. Humidity up to 95% RH. Altitude up to 2,000 m.

6,000 cycles at 80% DoD, 25°C, 0.5C, to 60% end of life, as printed. That result belongs to the stated depth of discharge, temperature, and current. It is not a calendar-life promise for every site in Bangladesh.

The reviewed LVTOPSUN catalog prints a 5-year warranty for this model. The sales poster may print 6 years. This page follows the catalog. Five years is the warranty period printed there. It is not split on that page into a separate performance warranty, and it is not a promise of a free replacement for every fault. The card supplied with the battery controls.

The catalog prints a maximum of 4 batteries in series and 4 in parallel, which is the stated path from 1.28 kWh toward 20.48 kWh. Use the same model and the manual's cable, breaker, and communication rules. Do not mix voltages.

The reviewed 12.8 V catalog page does not list CAN, RS485, or RS232. Confirm whether the inverter has a lithium profile for a 12.8 V battery before purchase.

No. Match 12.8 V, the current limits, and a lithium profile or BMS protocol that lists this model. A brand logo on the inverter is not approval.

There is no fixed backup time. A rough estimate is hours ≈ usable kWh × system efficiency ÷ average kW. 1.28 kWh at a 0.5 kW average is not the same result as at 2 kW. Temperature and inverter limits change it.

LVTS-128200-S4 is 200 Ah and 2.56 kWh. LVTS-128280-S4 is 280 Ah and 3.58 kWh. This listing is the 100 Ah, 1.28 kWh block.

SOLAR24 lists 16 units in stock. Ask before agreeing a delivery date outside the warehouse.

Match 12.8 V, 1.28 kWh, 9.85 kg, IP54, and the inverter's battery list. Keep the invoice and the serial number. The sales poster is not the datasheet.
