Maximum PV open-circuit voltage: 100 V. Supported battery types: lead-acid, LiFePO4 and lithium-ion. USB output: 5 V/2 A. Light/timer control and manual load switching support flexible DC load operation. MOSFET over-temperature protection activates above 85°C.
Applications
For off-grid solar battery charging and DC lighting projects that require light or timer load control. Importers and installation companies should select the current option, battery voltage and load configuration for each project.
Battery & PV Compatibility
Match the battery voltage and charging settings to the selected battery chemistry. The listed PV voltage is an open-circuit specification, not a guarantee that every panel configuration in that range suits every battery voltage. Confirm the solar array against the model instructions, including its cold-weather open-circuit voltage. Connect the battery first, then PV, and then the DC load.
OEM & Order Information
For SY4840B / SY4850B / SY4860B, send the required battery voltage, charging-current option, PV configuration, destination market and order quantity. Ask GERIXI sales to confirm logo, label and packaging customization availability, MOQ, quotation and technical documentation for the exact configuration.
FAQ
Can the 40 A / 50 A / 60 A configuration be supplied with our branding?
Send your selected model, 12 V, 24 V, 36 V, 48 V battery system and branding artwork. Sales will confirm the available customization scope and order requirements.
Which compliance documents apply to this PWM controller?
Request documents listing the exact model and confirm their scope against the destination market requirements. A certificate for another controller or series should not be assumed to cover this order.
What should be confirmed about warranty for this installation?
Provide the battery type, PV configuration and expected installation conditions. Obtain the written warranty period, exclusions and service procedure for the selected model before placing the order.
