Frequently Ask Questions

MOTOMA offers a variety of lithium batteries, including Lithium Polymer batteries, Cylindrical Lithium batteries and Lithium Iron Phosphate (LiFePO4) batteries, for different residential, commercial and industrial applications.

MOTOMA lithium batteries provide high energy density, lighter weight, faster charging, stable discharge voltage, low self-discharge and long cycle life. LiFePO4 technology also offers strong thermal stability, deep-discharge capability and improved environmental characteristics compared with traditional lead-acid batteries.

With proper use and operating conditions, MOTOMA lithium batteries can have an expected service life of up to approximately 15 years. Actual life depends on usage, temperature, charging conditions and the specific battery model.

Select a battery according to your application, required voltage, storage capacity, load demand, backup time and inverter compatibility. MOTOMA offers battery and BESS solutions across a range of capacities, and the sales or technical team can help confirm the appropriate model and system configuration for your project.

MOTOMA lists a 5-year warranty period for lithium battery units. Warranty coverage is subject to the applicable product model, sales terms and warranty conditions.

MOTOMA offers solar inverter solutions including off-grid inverters and hybrid inverters that can work with on-grid and off-grid system configurations.

An On-Grid inverter operates with the utility grid and converts solar DC power into AC power for local use or grid export. An Off-Grid inverter operates independently of the utility grid and normally works with battery storage. A Hybrid inverter combines solar, battery and grid operation, allowing energy to be used directly, stored in batteries or supplied from the grid depending on the system configuration.

The inverter should be selected according to your solar-array capacity, connected load, system voltage, battery configuration and whether the project needs grid-tied, off-grid or hybrid operation. Inverter capacity should be appropriately matched to the solar-panel capacity, and compatibility should be confirmed before installation.

Conversion efficiency varies by inverter model and operating conditions. MOTOMA‘s solar-system guidance notes that high-performance inverter platforms can achieve conversion efficiency of up to about 98%. Please refer to the datasheet of the specific inverter model for its rated efficiency.

MOTOMA states that its inverters generally carry a 2-year warranty, while selected IP65 inverter models carry a 5-year warranty. Please confirm the warranty terms for the specific model and market before purchase.

MOTOMA offers high-efficiency monocrystalline solar-panel solutions, including N-type TOPCon and bifacial technologies as well as Mono PERC product families for different installation requirements.

Solar-panel efficiency depends on the exact panel model and technology. MOTOMA‘s solar-system guidance notes that high-performance solar panels can reach efficiencies of up to about 25%. Please check the relevant product datasheet for the rated module efficiency.

MOTOMA solar panels are designed for long-term operation and are supplied with product and performance warranty coverage. MOTOMA lists a warranty period of up to 30 years for solar panels, subject to the applicable model and warranty terms.

The required number of panels depends on your electricity consumption, target solar-system capacity, panel wattage, available installation area, local sunlight conditions and system losses. A system designer should calculate the required array size from your actual energy demand and site conditions before selecting the final number of panels.

MOTOMA solar panels include product and performance warranty coverage, and MOTOMA lists a warranty period of up to 30 years for solar panels. The exact warranty terms should be confirmed for the specific panel model and sales region.
