FAQs

JSDSolar supplies hybrid and off-grid inverters, LiFePO4 batteries, residential energy storage systems, commercial BESS, portable power stations, solar street lights, and complete solar power configurations. Product availability and specifications may vary by market and project requirements.

Yes. A complete configuration may include solar panels, an inverter, battery storage, protection equipment, mounting accessories, and monitoring functions. The final system design depends on load requirements, installation conditions, local voltage standards, and expected backup duration.

The product range supports residential power, commercial energy management, off-grid properties, telecom backup, outdoor lighting, emergency power, and industrial applications. Each project should be reviewed according to its power demand and operating environment.

OEM services may cover branding, enclosure design, packaging, voltage configuration, communication settings, and selected technical specifications. Customization feasibility depends on product type, certification requirements, order quantity, and development scope.

Provide the required product type, quantity, destination country, application, voltage standard, power demand, and expected delivery schedule. For complete systems, sharing electricity consumption or a load list will help the technical team prepare a more suitable proposal.

Inverter selection should consider system type, rated load, surge power, grid voltage, battery voltage, solar input range, phase requirements, and backup functions. Future load expansion should also be considered during the selection process.

Battery capacity depends on daily electricity consumption, required backup hours, allowable depth of discharge, system losses, and available solar generation. Critical loads should be listed separately when backup power is a primary requirement.

On-grid systems work with the utility grid and usually have no independent backup. Off-grid systems operate without grid power and depend on batteries. Hybrid systems coordinate solar generation, batteries, and the grid to provide more flexible energy management.

LiFePO4 batteries offer long cycle life, stable voltage performance, good thermal characteristics, and lower routine maintenance than traditional lead-acid batteries. Their modular format also supports flexible capacity expansion in many storage applications.

Many JSDSolar battery models support parallel expansion. The added batteries should use compatible voltage, capacity, communication settings, and firmware. Expansion limits vary by model, and the inverter must also support the total battery capacity.

Compatibility depends on battery voltage, charging parameters, communication protocol, and inverter software. CAN or RS485 communication may require an approved protocol. The inverter model should be confirmed before placing an order.

Mixing batteries with different capacities, cell types, ages, or voltage platforms is generally not recommended. Differences between batteries may cause uneven charging and discharging. Use matched models and follow the approved parallel connection requirements.

A grid-connected system without battery backup normally shuts down during an outage for safety. A hybrid or off-grid system with batteries and backup output can continue supplying selected loads, provided the system has been configured correctly.

Equipment should be installed in a dry, ventilated location away from direct sunlight, water exposure, excessive heat, corrosive substances, and combustible materials. Installation clearances and environmental limits in the product manual must be followed.

Installation should be completed by qualified electrical or solar professionals familiar with local wiring rules, protection devices, grounding, battery safety, and commissioning procedures. Local permits and grid connection requirements should also be checked.

Provide the product model, serial number, installation date, system diagram, inverter and battery settings, alarm code, photos, and a clear description of the issue. Monitoring records or operating data can make remote diagnosis more accurate.

Warranty terms depend on the product model and sales agreement. Coverage generally applies to confirmed manufacturing or material defects under specified operating conditions. Damage caused by incorrect installation, misuse, unauthorized modification, or unsuitable environments may not be covered.

Yes. Remote assistance may include parameter checking, alarm analysis, communication troubleshooting, operating guidance, and installation review. Some issues may require an on-site inspection by a qualified local technician.

Replacement parts may be supplied according to product model, fault assessment, warranty status, and stock availability. Providing clear product identification helps the service team confirm the correct component and avoid mismatched replacements.

Keep ventilation areas clear, inspect cables and terminals, remove dust from equipment surfaces, check system alarms, and review operating data regularly. Solar panels should also be cleaned according to local dust, weather, and site conditions. Maintenance must follow the product manual and electrical safety procedures.
