Today, I will review another PWM charge controller, Esky LMS2430 PWM 30A Charge Controller
I reviewed Renogy Advanturer CTRL-ADV30-LCD before, which costs more than double the Esky LMS2430 charge controller price but has some benefits to it in terms of mounting and grounding. What I like about Esky charge controller is mainly their big LCD and the USB sockets.
Part Number: LMS2430
Amazon Link: Here
My Rating: 8.2/10
Esky LMS2430 PWM 30A Charge Controller Features:
- Built-in industrial micro-controller
- Temperature compensation
- Big LCD Screen to view status and adjust parameters
- Two 5V/1A USB sockets.
Esky LMS2430 PWM 30A Charge Controller Wiring:
Notes before Wiring:
- Never connect the solar panel to the charge controller without a battery.
- Suitable ONLY for sealed lead-acid, flooded or gel batteries.
- Make sure there is enough ventilation around the battery to release the gases.
- Connect the battery terminals to the charge controller FIRST before connecting the solar PV panel terminals.
- Temperature sensor polarity does NOT matter.
- Battery voltage sensor polarity DOES matter.
- That charge controller comes under so many brands (private labeling, same as many other components in the market) but I noticed that the one from Esky has a very sophisticated LCD display firmware that can show the real-time parameters and system data.
Esky LMS2430 PWM 30A Charge Controller Pros and Cons:
- 30A Max charging current.
- Parameters can be changed.
- Two USB Sockets.
- Temperature compensation, which prolongs the system life.
- Big LCD display.
- The manual is NOT clear at all and needs revision (but if you are patient, you will figure things out with the settings).
- The system where this controller is installed must be isolated from ground.
- LCD viewing angle, you cannot really see the data on the LCD if it is above your line of site.
Esky LMS2430 PWM 30A Charge Controller Troubleshooting:
Q: Charge indicator is off.
A: That means the PV panel is disconnected or reversed; make sure that the PV panel cables are properly wired to the charge controller with the right polarity.
Q: Load indicator is slowly flashing
A: that means an overload; reduce the loads connected to your system and see if the flashing stops.
Q: Load indicator is quickly flashing
A: That means a short circuit; check if the load terminals are properly wired or if there is a short circuit.
Q: When the load is connected, the battery status is full (or sufficient) but when the load is disconnected the battery status becomes (low-voltage protection mode).
A: That means bad/wrong battery connection or the battery wires diameter is too small. Check the battery connection and replace the connection wires with bigger ones if needed.
Q: Charging status immediately changed to “fully charged” right after the charging starts.
A: That means there is an overvoltage or overcurrent on the battery. Check if the maximum charging current setting of the charge controller is within the range of that of the battery. You can also reduce the charging voltage in the charge controller.
