Best Bang for your Buck$$

Reviewed in the United States on July 5, 2019

Size: 10AVerified Purchase

I've been a licensed professional commercial solar contractor for about 9 years, I've installed thousands of solar panels. I work with All of the big names in the industry. A senior couple at my church asked me to come up with a small backup powered solar capable system to run their CPA and charge cellphones, I only played with the little stuff so I searched Amazon to see what I could find, and I came across this 10 Amp PWM Charge Controller, well in short it works great I was amazed at how efficient it is and for less than $17.00 shipped to my door and perfect instructions even for beginners. When connected to a 24vdc battery bank it Auto Detects and I have it connected to a single 300 watt panel. I now want to test the BT-1 Adapter and see how it works. If anything changes I'll update it.

Bad controller

Reviewed in the United States on January 8, 2020

Size: 10AVerified Purchase

This controller did not even last one month. I started to get E01 and E08 error codes after 2 weeks usage on my lead acid batteries. Sometimes I would get an error code as soon as I hooked it up, and sometimes it would give me the error code after a few hours. I get these errors on three different battery banks that I have on my RV. I have installed this on my original solar suitcase (not my Eclipse model), replacing my 5 year old Viewstar controller.

I called Renogy and they told me to check the battery voltage and voltage at the controller terminals. I did previously and both were at 12.4 volts, which should be fine. So I guess this controller just does not work for me and I have to purchase another now, and reinstall it to my suitcase. Of course I will use a different model.

I actually again checked the voltage after the Renogy tech person seem to really question the voltage at the controller. I disconnected my Battery Tender, and the battery read 13.03 volts after settling down a few minutes, and it registered 12.94 at the controller terminals. So I am pretty sure my connection and wires are ok. By the way, now I am getting more error codes today, EO and EO2, the controller is going crazy with error codes, then it connects and seems to work after a while. Seems to connect and disconnect at random.

On a side note, the manual is somewhat vague, on page 14 it says to set the ‘charge voltage’ for a lithium battery (LiFepo4), but makes no mention of what voltage to set it at. There are about 21 different choices with no direction on what they mean or what to use. It goes from 12 volts up to 16 volts in .2 amounts of progression. On page 21, it talks about ‘Boost Voltage’, I have never heard of this, I know the 4 stages of charging a lead acid battery, but what is boost voltage? I guess I need to read up on this.

I have had many questions on my reviews for other Renogy products, and I have recently purchased several items; the 100aH LiFePO4 battery, a DC to DC charger (wait till I review the manual on this thing!), several PWM controllers, and several other smaller items. I am also trying to update my current review of the Eclipse suitcase with a major edit concerning the ‘plastic blocks’ that connect the legs to the frame but been have a little technical difficulty with the website.

I decided to install another solar controller due to all the problems with this one. I installed the Renogy Voyager 20A Waterproof Solar Controller, and so far it works perfect, no error codes. It also has a better manual and it at least tell me that the ‘charging voltage’ for lithium batteries is set at a default amount of 14.2 volts.

Bummer, my first negative review of a Renogy product, but it just did not work well.

Poor support for defective product

Reviewed in the United States on June 2, 2019

Size: 10AVerified Purchase

The short story is that Renogy has terrible support . I purchased a 50 watt Renogy solar panel. Blew out 1 controller then bought this Renogy controller. To their credit, this controller was smart enough to determine there was reverse polarity coming from the solar panel. This us odd since the wiring harness is idiot proof with red and black. Turns out it is a factory defect. It has been 2 weeks now and still waiting to hear back from Renogy on my support ticket. Even sent in a video of my multimeter test to prove the reverse polarity issue. Be warned dealing with this company.

Seems to work okay!

Reviewed in the United States on September 28, 2019

Size: 10AVerified Purchase

These are manufactured cheaply and you get what you pay for. I wasn't expecting anything substantial either. It proved to be useful for my project and that's what it counts. I have used Renogy products before and while they are cheap they are little bit better compared to other Chinese knock offs (Even I am certain this too is made in China) but the quality is slightly more tolerable for the price you pay.

This is clearly evident when you open the unit and find that there is no heat-sinks for the Mosfets. But I guess 10A PWM switching does not dissipate that much heat and they have gone away by replacing the back plate with an ALL-Plastic construction while they have redesigned the PCB with more substantial copper and tiny holes for air to circulate allowing the passive cooling of the Mosfets without using any heat-sink whatsoever.

Anyways, this is a Pulse width modulated (PWM) based Solar charge controller that is capable for charging Lithium Ion batteries (The main reason for choosing this over others) and I found that you can select "Max" battery charging voltage in the 12vDC and 24vDC ranges and allow further selections in small steps like 12.0, 12.2, 12.4, 12.6 etc for keeping the Lithium battery topped off by using solar panels as your primary source of power.

This Renogy Wanderer 10 Amp 12V/24V PWM Negative Ground Solar Charge Controller Regulator can accept wide range of DC voltage inputs (max - 50vDC) and will bulk charge your battery (as much as your solar panel can deliver) and pump all that power in AMPs directly into your battery and as the battery voltage reaches critical value (settable by user for Li-Ion) it starts to reduce the AMPs and slowly and safely reaching the specified value set by the user. Once the battery voltage is reached it will totally stop charging it even if the solar panel is delivering full power on sunny days.

PS: Depending on the battery types the float charging and bulk charging algorithms change which is good to know. The manual has the full details on types of batteries that it supports (Including lithium Ion) and good old Flooded Lead Acid 12/24 and GEL type etc.

Rating the product with four stars!

Simple and works perfect for my RV

Reviewed in Canada on March 16, 2019

Size: 30AVerified Purchase

Using this controller with 2x 100W panel of the same company. It's been in my RV for one year now.
It doesn't have any advance options on it but that's what I like about it. I just installed it near my battery in a cabinet and forget about it.

It does a good job for charging my two RV batteries. I even didn't removed my battery over the winter and it keept them just at the right charge.
I don't use the temperature sensor yet, but I just bought it couple weeks ago and it should make it event better.

We use our setup just to spend 3-5 days off the grid and increase the number of place we can go camping. If you are not an hardcore off the grid person, this charge controller is perfect for you and not too expensive.

Ordered Positive Ground by accident....the headline on the ad was clear enough but I was in a hurry.

Reviewed in Canada on June 2, 2020

Size: 10A Positive GroundVerified Purchase

At $20 these are a good value for a stand alone solar charge controller, though for another $5 I would recommend getting the more common negative ground version of this model.

Positive ground is a bit cheaper to manufacture (cheaper and small MOSFETS apparently), but this benefit is outweighed by other potential issues if connected to a trailer with a negative ground system. I haven't seen a Positively Grounded vehicle since the 1960's.

Well built, work as intended in a stand alone solar charging system but I won't use this to charge a battery in a negatively grounded trailer or vehicle.

As stand alone battery chargers these would work well and I will likely build such a system in the near future.

Nice charge controller but small connection terminals and USB won't work without a battery attached

Reviewed in Canada on June 28, 2020

Size: 10AVerified Purchase

I have a 50W panel which I figured would be handy for camping or emergencies. It came with a super cheap charge controller but I wanted something that provided a bit more info and also permit easy USB charging.

I should have read up on these a bit more but after hooking it up I discovered that it won't operate unless there's a 12V battery attached for it to charge. While this is a very useful feature, I was hoping the USB ports would operate on their own. Live and learn.

The User interface is pretty simple and offers enough options to let you operate with a few different types of setups (battery types etc)

The case is plastic ao might be less durable and won't offer a free heatsink for the electronics inside (I mounted it on the back of the panel with some velcro).

Only other complaint is the screw down terminals are rather small: I purchased some SAE connectors to connect to the panel and they used 10GA wire which while overkill *barely* fit into the holes in the case.

Too early to tell but not what I expected

Reviewed in Canada on October 20, 2020

Size: 10AVerified Purchase

I already had a PWM controller for my solar panel but since winter is coming and this was was advertized as having temperature compensation I thought I'd get it to help my batteries . When it came there was no sign of any temperature sensor so I can only assume ( rightly or wrongly) that there's something internal that somehow adjusts charge based on ambient temperatue of contoller. The other dissapointment ( my mistake not paying attn to specs) is the 12 awg terminals. I purchased 10 awg cables to prevent voltage drop which means I'll have to buy a terminal block to connect things up.
