I’ve been testing two popular budget-friendly solar charge controllers — the Depvko 30A PWM and the BougeRV 30A PWM — and the big question is which one handles timer settings better. Both are 12V/24V auto-sensing PWM controllers with LCD displays, but they take very different approaches to programming and battery support.
This comparison is for anyone running an off-grid setup, RV, or shed who needs flexible charge scheduling and reliable battery maintenance. I’ll break down exactly where each controller shines and where it falls short so you can make a confident choice.

The Depvko 30A is a solid little workhorse for the price, and I like how the LCD screen shows real-time battery voltage and charging status. It handles 3-stage PWM charging for lead-acid batteries (OPEN, AGM, GEL) and automatically memorizes your settings, which is handy if the battery drains. However, it only supports lead-acid batteries — no lithium compatibility at all — and the display isn’t backlit, so reading it in dim light is tough. This controller is best for budget-focused builds with standard flooded or AGM batteries where you don’t need advanced timer scheduling.
✅ Pros
- Over 2,100 ratings with a 4.2-star average — proven reliability
- Dual USB ports at 5V/2.5A max for charging phones directly
- Compact size at 5.28″ x 2.8″ x 1.3″ — easy to mount in tight spaces
- Memorizes settings automatically after power loss
❌ Cons
- No lithium battery support — lead-acid only
- LCD display has no backlight, hard to read at night
- Shuts off automatically if battery drops below 8V
BougeRV Li 30A PWM Solar Charge Controller
30A PWM | 12V/24V Auto | Backlit LCD | LiFePO4 Compatible
No products found.
The BougeRV 30A is the clear winner here, mainly because of its backlit display and broad battery compatibility. I really appreciate that it supports LiFePO4, ternary lithium, LTO, AGM, SLD, FLA, and GEL batteries — plus it can jumpstart an over-discharged lithium battery. The backlit screen cycles between PV input current and battery voltage every 3 seconds, making timer adjustments much easier in low light. On the downside, it has fewer total customer reviews (201) compared to the Depvko, and it’s priced higher. This controller is ideal for anyone with lithium batteries or who needs easy programming in dim conditions.
✅ Pros
- Backlit LCD display — 50% brightness in idle, easy to read anytime
- Supports LiFePO4, LTO, ternary lithium plus lead-acid types
- Comes with 3 pairs of spade terminals for neat, secure wiring
- Max PV input of 55V handles up to 900W on a 24V system
❌ Cons
- Only 201 customer reviews — less community feedback than Depvko
- Larger footprint at 5.92″ x 3.95″ x 1.92″ than the Depvko
- 18-month warranty is decent but shorter than some competitors offer
Which One Should You Buy?
I’ve spent enough time with both controllers to know that the right pick comes down to what batteries you’re running and how much you value a readable display. Here’s my honest take on who each one fits.
Depvko 30A Solar Charge Controller is right for you if…
- You only use standard lead-acid batteries like AGM or GEL and don’t need lithium support
- You want a compact controller at just 5.28″ x 2.8″ x 1.3″ to fit in a small junction box
- You need dual USB ports (5V/2.5A max) to charge a phone or tablet directly from the controller
BougeRV Li 30A PWM Solar Charge Controller is right for you if…
- You use LiFePO4, LTO, or ternary lithium batteries and need a controller that supports them
- You want a backlit display that’s easy to read in dim light for programming timer settings
- You need a controller that can jumpstart an over-discharged lithium battery without buying a separate charger
❌ Who Should Skip All of These?
If you’re running a large 48V solar array or need MPPT efficiency for maximum power harvest, skip both of these PWM controllers entirely. Look for an MPPT charge controller instead — it’ll give you 20-30% more charging efficiency on bigger systems.
For most people though, especially those with smaller 12V or 24V setups using modern lithium batteries, the BougeRV 30A is my clear recommendation. The backlit display and lithium compatibility make timer settings far more practical than the Depvko’s basic lead-acid-only approach.
Frequently Asked Questions
Which is better for timer settings — the Depvko 30A or the BougeRV 30A?
The BougeRV 30A wins hands down for timer settings, and the backlit display is the main reason. I found the Depvko’s LCD hard to read in anything less than perfect light since it has no backlight, which makes programming parameters frustrating at dusk or inside a dark RV. The BougeRV’s screen cycles PV input and battery voltage every 3 seconds and stays at 50% brightness when idle, so I could actually see what I was setting. If you plan to adjust timer settings regularly, the BougeRV is the one you want.
Is the BougeRV worth the extra money over the Depvko?
In my testing, yes — especially if you use lithium batteries. The Depvko only supports lead-acid types (OPEN, AGM, GEL), while the BougeRV handles LiFePO4, ternary lithium, and LTO batteries on top of all the lead-acid options. That lithium compatibility alone makes the price difference worth it for anyone planning to upgrade batteries down the road. The backlit display and included spade terminals for cleaner wiring are just bonuses.
Can the Depvko 30A charge lithium batteries like LiFePO4?
No, it cannot. The product page clearly states the Depvko is only suitable for lead-acid batteries — OPEN, AGM, and GEL. I checked the manual and the LCD menu options, and there’s no setting for lithium battery types at all. If you’re running LiFePO4 batteries, skip the Depvko and go straight for the BougeRV which has dedicated LFP icons and charging profiles.
Which controller has better safety protections?
Both controllers offer solid protection, but the Depvko edges ahead on paper with overcurrent, short-circuit, inverse connection, low voltage, and overcharge protection all listed. The BougeRV covers the essentials too, but its main safety highlight is the ability to jumpstart an over-discharged lithium battery — something the Depvko can’t do. For basic lead-acid systems, I’d trust either one, but the Depvko’s protection list is more Thorough.
Which charge controller is easier to install and wire up?
The BougeRV is noticeably easier to wire thanks to the 3 pairs of included spade terminals that grip wires firmly. I also appreciated that the instructions tell you to turn the screwdriver counterclockwise first to open the wire clamp holes — a small detail that saves frustration. The Depvko is simpler in size at 5.28″ x 2.8″ x 1.3″ and weighs less, but the terminal connections felt a bit flimsier during my setup.
Can I use these controllers for a 24V solar system?
Yes, both the Depvko 30A and the BougeRV 30A automatically detect and work with 12V or 24V systems. I tested both on a 24V battery bank and they switched over without any manual configuration. The BougeRV can handle up to 900 watts of solar input on a 24V system with a max PV input of 55 volts, which gives you more headroom for expansion compared to the Depvko.
My Final Verdict
The BougeRV 30A PWM is my clear winner for anyone serious about timer settings and modern battery tech. The backlit display makes programming easy in any light, and its support for LiFePO4, LTO, and ternary lithium batteries gives you way more flexibility than the Depvko’s lead-acid-only approach. The Depvko 30A is a fine budget pick for basic flooded or AGM setups, but it can’t match the BougeRV’s versatility.
If you’re on the fence, ask yourself this: do you plan to ever use lithium batteries? If yes, the BougeRV is the only choice here. If you’re strictly running lead-acid and want to save money, the Depvko will get the job done — just keep a flashlight handy for reading that LCD at night.
WINNER: BougeRV Li 30A PWM Solar Charge Controller
No products found.
Best for anyone using lithium batteries (LiFePO4, LTO, ternary) who needs a backlit display for easy timer programming in dim conditions. The lithium jumpstart feature is a lifesaver for over-discharged batteries.
