Specifications and feature information from the original product graphics

 

Some of the original KKSY product information was presented only inside graphics. The following text makes those facts searchable and easier for a buyer to check. The visual specification card and the production batch should be confirmed before a quotation is issued.

 

 

 

Product identity shown in the original visual

 

• Product type: 60A 12V/24V MPPT charge controller for solar panels.


• Product family: KKSY series, with the visual identifying the 50A/60A version as KKSY-8905.


• Customization: ODM/OEM individual customization, including customized appearance and color box.


• Buyer-facing controls and indicators: LCD screen, setting buttons, PV/BAT/LOAD status icons, charging current, power, temperature and amp-hour readings.


 

 

 

 

Functions and protections transcribed from the feature graphics

 

The original feature graphic lists built-in circuit protection, automatic voltage identification, peak power tracking, compatible battery selection and a large LCD screen. The protection graphic lists short-circuit protection, open-circuit protection, over-current protection, over-charge protection, over-discharge protection and polarity protection.

 

 

One comparison graphic labels a 97% high-conversion/tracking figure for the MPPT example. Treat this as a graphic reference rather than a blanket performance guarantee: actual output depends on PV Voc/Vmp, temperature, wiring, battery state and test conditions.

 

 

 

Battery types shown in the original graphics

 

The graphics show lead-acid, AGM, GEL and lithium batteries. The accompanying text lists AGM, GEL, sealed lead-acid, wet lead-acid, lead-crystal, Li-ion and LiFePO4 options, with use cases including starter, deep-cycle, marine and powersports batteries. Select the charging profile from the actual battery datasheet; do not use a lithium setting for a lead-acid bank or the reverse.

How to use the 60A 12V/24V controller in a real installation

 

1. Confirm that the battery bank is a 12V or 24V system and select the correct chemistry/charging profile.


2. Measure the PV array open-circuit voltage in the coldest expected condition. Keep the measured Voc below the applicable limit shown for the selected model; for KKSY-8905, the product graphic shows <100V.


3. Connect the battery first, checking polarity and cable size, then connect the PV input, and connect the DC load last. This battery-first sequence allows automatic voltage identification to work correctly.


4. Use the LCD to check PV voltage/current, battery voltage, load status, temperature and amp-hour information. Record the values during commissioning so a later fault can be compared with a known-good baseline.


5. Leave ventilation space around the fan and keep the controller away from direct rain, condensation and high-temperature enclosures.


 

 

 

 

Daily problems and practical answers

 

 

 

 

 

 

 

 

 

 

 

Problem seen by the user	Checks to make before requesting support
LCD is blank	Check battery polarity, battery voltage, terminal tightness and the controller fuse/protection state. The unit needs a correctly connected battery before PV testing.
PV voltage is present but charging current is zero	Check PV polarity, PV Voc, shading, the selected battery profile and whether the battery is already at the charge limit. Compare the LCD PV and BAT readings.
PV over-voltage warning	Measure cold-weather Voc and reduce the number of series panels or choose a higher-voltage controller. Do not keep reconnecting an array that exceeds the controller limit.
Battery never reaches the expected voltage	Confirm the chemistry setting, battery capacity, cable voltage drop and whether the array has enough wattage for the load. Lithium and lead-acid voltage targets are not interchangeable.
Load output switches off	Check load current, startup surge, short-circuit protection and the configured load timer/LVD setting. Test the controller with the load disconnected before reconnecting it.
Fan runs continuously or the case becomes hot	Check ventilation, ambient temperature, load current and cable losses. Keep the vents clear and send a photo of the installation plus LCD temperature for diagnosis.
