The SYB-48V Series is a PWM solar charge controller range for buyers planning 12V, 24V, 36V or 48V battery systems. It is suited to off-grid battery charging and DC lighting projects where automatic system recognition, light or timer control, and a defined charging-current option matter. This guide helps importers, distributors and installation companies prepare a clear bulk-order enquiry.
SYB-48V specifications at a glance
- Models: SY4840B, SY4850B and SY4860B
- Rated charging current: 40A, 50A or 60A
- Battery system voltage: 12V, 24V, 36V or 48V with automatic recognition
- Controller type: PWM
- Maximum PV open-circuit voltage: 100V
- Supported battery types: lead-acid, LiFePO4 and lithium-ion
- USB output: 5V/2A
- Enclosure size: 183 x 136 x 53 mm
The series also supports light and timer control, manual load switching, and MOSFET over-temperature protection that activates above 85°C. The 100V value is the PV open-circuit limit; it is not a promise that every panel arrangement suits every battery voltage. Buyers should check cold-weather PV voltage and the exact model instructions before placing an order.
Where this PWM controller fits
SYB-48V is a practical option for small and medium off-grid solar battery systems, DC lighting installations, remote equipment with controlled loads, and distributor product packages covering several battery voltages. The 40A, 50A and 60A choices allow a buyer to align the controller with the planned charging current instead of treating one rating as suitable for every project.
For installation planning, match the selected battery voltage and charging settings to the battery chemistry. Confirm the PV array against the controller limit, connect the battery first, then PV, and finally the DC load. A project requiring AC output or inverter functions needs a separate inverter; this PWM controller should not be presented as an inverter.
What a B2B buyer should confirm before a quotation
For a wholesale or bulk order, send the preferred model, battery voltage, charging-current option, PV configuration, destination market and quantity. Ask the supplier to confirm the available logo, label and packaging customization, MOQ, quotation and technical documentation for the exact SY4840B, SY4850B or SY4860B configuration. Any compliance documents and warranty terms should be checked for the ordered model and destination requirements rather than assumed from another series.
GERIXI can review the project information and advise on the appropriate configuration. See the SYB-48V product details for the product information, then use the contact page to request supplier feedback, a quotation or distributor-order discussion. Include the battery type, PV details, load profile and expected quantity so the enquiry can be checked efficiently.
