Send your inverter model, required capacity and destination market. Ask an Engineer What is a stackable battery system? + A stackable battery system uses modular lithium battery units that are physically stacked and electrically connected to increase total storage. It allows customers to start with a smaller capacity and add modules later. How many battery modules can be connected? + The 5.12kWh low-voltage model supports up to 16 units in parallel, reaching 81.92kWh. Other stackable product families can support different capacity ranges, so the final configuration should be confirmed by model. Which inverter brands are compatible? + GSL stackable batteries work with many leading hybrid inverter platforms, including Deye, Growatt, Victron, GoodWe, Solis and SMA. Compatibility depends on the exact model and firmware; our engineers will verify your inverter before order confirmation. Can the battery be used for on-grid and off-grid systems? + Yes. Depending on the inverter and system design, the battery can support off-grid power, grid-connected solar self-consumption and hybrid systems with backup capability. What OEM and ODM options are available? + Available customization can include logo, enclosure color and appearance, capacity configuration, communication protocol, product label, manuals and packaging. Feasibility and MOQ depend on the requested scope. What information is needed for a quotation? + Please share the required capacity, quantity, inverter brand and model, on-grid/off-grid application, destination country, OEM requirements and expected delivery schedule.
