51.2V 100AH Lithium Solar Battery
This is the fully documented lithium solar battery model in the catalogue: a wall-mounted unit presented for solar energy storage in homes and small sites. The figures below are the model's own specification as listed by the supplier. Note that the product name and the specification table use their values as listed — the name carries the headline rating, and the table gives the electrical values in detail — so read the two together rather than assuming one replaces the other.

The battery is presented for the daily cycle work of a solar system: charge from the array when production exceeds the load, discharge when the building draws more than the array provides or when the grid is unavailable and the system is configured for backup. Its information material highlights long battery life and light weight for its class, and its characteristic curves — charge, discharge, cycle and self-discharge behaviour — are published with the product for buyers who want to check performance shape rather than headline numbers alone.
Fit and use
The wall-mounted format suits homes and small sites where floor space is limited and the battery needs to sit close to the inverter and distribution board. Before ordering, walk through the practical checks: the loads you intend to run from the battery, the inverter it will pair with, the wall and ventilation where it will be mounted, and the temperature range of that space against the operating ranges in the table. The selection guide on this site takes those questions one by one.
Warranty and terms
The warranty for this battery model is 3 years, as stated in the product's own question-and-answer material. That term belongs to this model; other products in the catalogue carry their own terms, so confirm the warranty wording for the exact model in your quotation. Before ordering, confirm minimum order quantity and lead time for your configuration.
Certificates available upon request. Ask for the documents for this model together with the quotation, and check that the model named in the documents matches the model you are ordering.
Pairing and system fit
A battery never works alone, and its fit is decided by the equipment around it. The inverter it pairs with must be arranged for the battery's voltage values as listed, and the system's controls must agree on when the battery charges, when it discharges and what happens when the grid drops. If you already have an inverter, bring its documentation to the enquiry rather than its brand name alone: compatibility is read from documents, and a pairing that looks obvious from two brochures can fail on a single line of a specification table.
Physical fit is the other half. The unit's weight and dimensions in the table are the figures to check against the wall, the doorway and the working space around the mounting position, and the temperature ranges are the figures to check against the hottest and coldest weeks in that space. A short enquiry that includes the load list, the inverter documentation and a sentence about the mounting space will get a firmer answer about this model than a long enquiry that only asks its price.
