51.2V 100Ah Solid State Solar Battery For Home Use

Last verified 2026-10-06.

• Legal manufacturer as printed: Shenzhen Delong Energy Technology Co., Ltd
• The maker describes this 51.2V 100Ah (5120Wh) LFP home battery as using a semi-solid, solid-liquid hybrid electrolyte internally.
• The printed name says solid state, but the maker's own description is semi-solid (hybrid) electrolyte, so review.solar records it as a semi-solid LFP battery, not a fully solid-state one.
• The product page offers only an inquiry form, with no price and no named market, so its commercial availability to Australian buyers is not stated.
• The page remains unscored: round-trip efficiency is not established, exact governing warranty terms remain unconfirmed and no exact certification listing was independently recovered. The readable datasheet and generic one-year/five-year service terms do not establish the product page ten-year headline as model-specific coverage.
• This record is not joined to any scored or evidence record on review.solar.
• The exact LVSW5.0 two-page maker datasheet has now been visually read. It repeats 51.2 V, 100 Ah and 5,120 Wh battery energy, but does not establish measured usable energy or a round-trip efficiency result. No printed revision date is visible; the upload directory is not treated as one.
• The sheet distinguishes recommended charging at 30 A from a 50 A maximum, and recommended discharge at 50 A from a 100 A maximum and 105 A peak for five seconds. Its 3-5 kW recommended load is not an independently established continuous AC output or surge-power guarantee. Nominal voltage and current limits are not multiplied into a score.
• The exact technical sheet gives 57.6 V +/- 0.2 V charging cut-off and 44.8 V +/- 0.2 V discharge cut-off, M8 terminals, a metal enclosure and RS485/CAN communication. Interface presence and general compatibility marketing do not establish a particular approved inverter, firmware version, open API or local/cloud service.
• Charging is specified from 0 C to +45 C and discharge from -5 C to +55 C. These distinct limits are preserved rather than using a single operating-temperature headline. The sheet lists at least 6,500 cycles and a twelve-year designed life without a DoD, temperature, charge rate or retained-capacity endpoint; neither headline establishes a performance warranty.
• Delong now publishes generic warranty-related service conditions on its support page. After its technical team confirms a product-quality fault from requested evidence, it offers replacement within one year, free faulty-product replacement parts after one year and within five years, and technical support with paid parts after five years. Installation of replacement parts follows its guidance or a locally hired professional; this is not a blanket labour-cost promise.
• Those support terms exclude damage from use beyond specified power, improper operation or installation contrary to guidance. They do not name LVSW5.0, define commencement or an effective sales cohort, or establish ten-year capacity/throughput coverage, registration, transfer, claim deadlines, freight or removal/reinstallation reimbursement. The product page ten-year heading is explained as up to ten years of after-sales service; exact governing warranty terms remain unconfirmed.
• The maker sheet still calls the cell type solid-state, while the exact product description calls the electrolyte semi-solid, solid-liquid hybrid LFP. That boundary is retained. Generic safety, Grade A cell and certification marketing does not establish a cell manufacturer, independent fire result or exact safety approval.
• Round-trip efficiency is not established and no exact certification listing was independently recovered. The new technical and service evidence adds reader depth while three promotion gates remain open. No model pairing, scored configuration, sale-market eligibility or Australian availability claim is added.

• Delong LVSW5.0 product pagehttps://www.delongtop.com/solid-state-battery/51-2v-100ah-solid-state-solar-battery-lvsw5/

  The maker's product page prints the product name and model LVSW5.0, describes a semi-solid, solid-liquid hybrid LFP electrolyte, gives a spec table with generic certification marks, and separately mentions up to 10 years of after-sales service.

• Delong company homepagehttps://www.delongtop.com/

  The maker's homepage prints the legal company name and its Shenzhen address.

• Delong LVSW5.0 exact two-page technical datasheethttps://www.delongtop.com/wp-content/uploads/2024/07/LVSW5.0-Datasheet-51.2V-100Ah-Solid-State-Battery.pdf

  Image-only source visually read. Nominal energy, recommended/maximum/peak current, cut-off voltages, separate thermal limits and unsupported cycle/life measurement basis retained. No printed revision date.

• Delong public support-page warranty-related service conditionshttps://www.delongtop.com/support/

  One-year replacement, years one-five free parts, later paid parts/technical support after fault confirmation. Generic scope, no exact LVSW5.0/ten-year governing entitlement or complete costs/cohort terms.
