LVTOPSUN LVTS-256100-S4 25.6V 100Ah Battery

The selling price on this page is ৳45,000. The regular price is ৳51,600. That price is for the battery. It does not include an inverter, solar panels, cables, protection gear, or installation.

No. LVTS-256100-S4 stores 2.56 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 25.6 V. The LVTS-256100 user manual prints charge voltage 28.08 V and discharge range 22.8 V to 28.08 V.

Charge current 50 A. Charge power on the catalog page is 1,280 W. Discharge current 100 A. Discharge power on the catalog page is 2,560 W. Short-circuit current is printed as about 2,000 A. A maximum on a datasheet is not a promise that every inverter will use it.

The sales image prints 2.56 kg beside a weight icon. That figure tracks the stored energy, not a measured mass. The reviewed sheet lists 26 kg on the catalog; the user manual prints 25.8 kg with the wall bracket. This page uses the sheet.

The user manual shows a rack-mounted and a wall-mounted LVTS-256100. This listing is the S4 rack form on the product image. Electrical ratings match that manual. Size on the reviewed sheet: 330 × 135 × 420 mm (manual: H420 × W330 × D135 mm). Weight: 26 kg on the catalog; the user manual prints 25.8 kg with the wall bracket.

Ingress protection on the reviewed sheet is IP20. Match the manual for sun, rain, and ventilation. An IP rating is not permission to leave the battery in standing water.

Catalog working temperature −20°C to 60°C. The user manual prints charge 0°C to 55°C and discharge −20°C to 55°C.

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 2 batteries in series and 4 in parallel. Use the same model and the manual's cable, breaker, and communication rules. Do not mix voltages.

The reviewed LVTS-256100 user manual leaves communication mode blank. Do not assume CAN until the manual supplied with the unit lists it.

No. Match 25.6 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. 2.56 kWh at a 0.5 kW average is not the same result as at 2 kW. Temperature and inverter limits change it.

LVTS-256100-WALL is the wall-mounted listing of the same 25.6 V 100 Ah ratings. The stored energy does not change with the bracket. The SOLAR24 prices are different.

SOLAR24 lists 12 units in stock. Ask before agreeing a delivery date outside the warehouse.

Match 25.6 V, 2.56 kWh, 26 kg on the catalog; the user manual prints 25.8 kg with the wall bracket, IP20, and the inverter's battery list. Keep the invoice and the serial number. The sales poster is not the datasheet.
