FAQ for solar controllers, inverters and battery chargers

Yes. Gerixi is a China-based manufacturer focusing on solar charge controllers, power inverters and battery chargers, with factory production and OEM/ODM support.

The factory is located in Zhaoqing Hi-Tech Zone, Sihui, Zhaoqing, Guangdong, P.R. China, close to Guangzhou and the Pearl River Delta supply chain.

Gerixi mainly serves renewable energy distributors, solar system retailers, installers, project contractors and OEM/ODM partners in overseas markets.

Yes. Logo, label, product color, carton marking and packaging customization can be discussed according to quantity, product family and project requirements.

OEM and ODM options can include product color, labeling, interface details and packaging, subject to the selected model and order quantity.

Please provide solar panel wattage and open-circuit voltage, battery voltage, battery type, required charging current and whether the system needs timing or load control functions.

PWM controllers are often used for simple and cost-sensitive DC systems. MPPT controllers are preferred when the buyer needs higher charging efficiency, wider PV input flexibility or larger solar systems.

The product catalog lists support for lead-acid batteries, LiFePO4 batteries and lithium batteries on relevant controller models. Final battery compatibility should be confirmed by model.

Compatibility depends on the product model, battery voltage and charging requirements. Confirm the final configuration with the Gerixi team before ordering.

The catalog material notes that the controller should connect to the battery first, then the PV panel, then the DC load. This helps the controller identify the battery voltage correctly.

Before first wiring, confirm the battery voltage is high enough for the controller to identify the system voltage, and confirm the solar panel open-circuit voltage is within the selected model range.

Pure sine wave output is usually better for refrigerators, pumps, motors and sensitive electronics. Modified wave inverters can be suitable for simple loads and cost-sensitive markets.

The product catalog includes inverter input options such as 12V, 24V, 48V, 60V and 72V DC, with some dual-voltage or multi-voltage options depending on model family.

Confirm battery voltage, continuous load, starting surge, output waveform and expected runtime before selecting an inverter family.

Catalog material lists common output options including 110V, 120V, 220V, 230V and 240V AC, with 50Hz or 60Hz options. Final configuration should match the destination market.

Many inverter models list low-voltage, over-voltage, over-temperature, overload and short-circuit protection. Some models also include battery reverse-connection protection. Protection details are model-specific.

Several catalog models include LCD or digital displays showing battery voltage, output voltage, output power and fault codes, which helps users identify operating status quickly.

Common applications include residential solar backup, RV and boat power, outdoor lighting, monitoring systems, small business backup and battery maintenance.

Buyers should confirm battery voltage, solar panel input voltage, charging current, inverter output power, local AC voltage, plug type, packaging needs and certification document requirements.

Yes. The application materials include RV, boat and outdoor power scenarios. Buyers should confirm battery voltage, appliance list, maximum starting load, socket type and local output voltage.

Yes. Indoor backup applications can support essential loads such as lights, routers, fans, computers, POS systems and small appliances when the system is matched correctly.

An off-grid system is designed to operate independently from utility power. A backup system normally supports selected loads when the utility supply is interrupted.

Yes. Share the application, system voltage, load information, battery type and target market so the team can suggest suitable product families.

Sample orders can be discussed before bulk purchase so buyers can test the product in their local market. Shipping cost and lead time are confirmed by destination.

The standard warranty period is one year. If a confirmed product issue occurs during this period, Gerixi can support spare parts and repair guidance according to the case.

Many ready or standard products can be tested and shipped within about 7 days, but the final schedule depends on product type, order quantity and actual production plan.

Customized logo, color, label, packaging and carton marking usually depend on MOQ, product type and production schedule. Please send the required customization details for confirmation.

Common payment terms are 30% deposit and 70% balance by T/T before shipment. Final terms should be confirmed with the sales team for each order.

Buyers can request product catalogs, model specifications, user manuals, certification documents and quotation information according to the selected product family.

No. The supplied CE and RoHS documents cover specific inverter models and should be checked against the exact model being purchased.

Send product category, model if known, required quantity, target price, destination port or country, battery voltage, output voltage, plug type, logo option and packaging requirement.

Available materials may include product catalogs, datasheets, manuals and applicable certification documents.
