Solar Home Systems & PayGo Solutions

Choose from the required loads first, then confirm daily operating hours and starting currents. Lighting and phone charging generally fit the smaller 15W to 80W range. TVs, fans and broader household loads require the 150W to 500W range, while a refrigerator or shop load requires review of the 1000W system and its pure sine wave inverter.

List each appliance, its rated watts and expected hours of use, then multiply watts by hours and add the results. Include charging losses and a practical reserve when selecting the battery and panel. For refrigerators, freezers and fans, use measured or published consumption where available rather than assuming the appliance runs at its maximum rating continuously.

PayGo activation is code based. The user enters an issued code through the built-in 4×4 keypad, and the system accepts the usage period defined by the distributor. Plans can be set as daily, monthly or yearly arrangements. The documented activation method is keypad-based code entry; the exact payment workflow should be confirmed during configuration.

Match the appliance voltage, rated power, connector and expected operating time with the selected system. Solar DC TVs are available from 19 to 65 inch and 10W to 30W. DC freezers cover 50 to 600L and 45W to 150W, while refrigerators cover 60 to 245L and 72W to 130W. Confirm battery reserve before combining appliances.

A complete kit includes a solar panel with a 5m cable, a LiFePO4 battery, a charge controller and output ports. The smaller models provide USB 5V ×2 and DC 12V ×6 connections, while larger models also provide AC output. Matched DC appliances can be included when required, and the final combination should be confirmed against the system rating.

DC appliances avoid inverter conversion and can reduce conversion losses when their voltage and connectors match the system. AC appliances require an inverter and must remain within its continuous and starting-load limits. The 150W model uses a 150W modified sine wave inverter. The 300W, 500W and 1000W models use pure sine wave inverters, with the 1000W model specified for TVs and refrigerators.

CE and RoHS documents are available for applicable products. Document availability should be checked for each selected model and included in the procurement file. A technical review can also confirm panel rating, battery capacity, controller rating, inverter type, output arrangement and appliance combination before the quotation is finalized.

Provide the target system range, panel and battery configuration, required AC and DC outputs, appliance list, operating voltage, branding and packaging requirements. Also specify the intended PayGo plan structure, keypad activation requirements, documents needed and any preferred appliance combination. For OEM review, include product labels, packaging artwork and the required configuration so the technical scope can be checked before quotation.
