FAQ
Q1: How to choose the correct solar charge controller for your system?
A1: It based on the solar array's current and the solar system's voltage.You should make sure the charge controller can handle the amount of power and current produced by your panels. For example, I have two 100W solar panels one of the Isc is 5.5A and the system voltage is 12V. Two connected in series 5.5*2=11A, 24V system voltage. Then you will need at least 11Amps, However, you need to factor in an additional 25% due to environmental factors. This brings the minimum amps that this charger controller must have to 13.75 amps. In this example, you would need a 24V,≥15A solar charge controller.
Q2: What is difference between PWM and MPPT how to choose?
A2: The main difference between PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking) charge control devices is that the MPPT devices are more efficient. MPPT charge control devices have 30 % more efficient in charge efficiency according to PWM type. Panel voltage and battery voltage should be matched in PWM systems. In MPPT systems, the panel series are allowed to have a higher voltage than batteries. This means more flexibility for system growth. Depending on your budget, for the small off-grid system（＜200W）, you can consider PWM for economy. For bigger off-grid system(such as ＞200W), MPPT is the clear choice.
Q3: Operating and setting?
A3: Left Buttoni) In Setting: Long press- Enter the non-setting page; Short press- Enter the next setting page. ii) Main Level: Long press- Enter the setting page；Short press- Enter the next non-setting page. Right Button i) In Setting: Long press- No function; Short press- To adjust parameter. ii) Main Level: Long press- Load short circuit protection recovery; Short press- Load switch (in manual mode).
Q4: Recover solution from error codes?
A4: E01: Over discharged; recover once the battery voltage return to the normal level. Load is allowed to turn on then. E02: Battery over voltage; recover once the battery voltage return to normal level. E04: Load short circuit. E07: Device over heating; Get the device cooler to decrease the temperature. E10:PV over voltage; To decrease the input voltage.

Not what I would expect from Newpowa. I tested it with an inexpensive PWM controller that I have used for several months. Same sun, same batteries, same usage, same wiring. The Newpowa should have charged the batteries by midday, in fact the batteries never charged up. After three days, I replaced the Newpowa with my old charge controller and the batteries were charged by midday just as I expected. I don't know what is going on with these but I think they are JUNK! Anyone want one for free???

I bought another generic controller and it works much better, gets me to 14.4v on my LIFEPO4.

Scans thru all criteria but speed is just slightly too fast for my eyes to focus. Does it's thing and tracks with mppt variations. Love the big wire gauge terminals at the bottom which sold me. Display could be back lite for less eye strain. Well constructed and attractive package container.

An excellent bit of kit for any survivalist or anyone looking to live off grid. First off, the versatility of this solar charge controller is outstanding. It’s adjustable for Gel, AGM, Liquid, and Lithium batteries, making it perfect for any off-grid setup. Whether you’re charging a small lithium battery for your electronics or a larger AGM battery for your RV, this controller handles it all with ease.The 12V/24V compatibility is a huge plus. It automatically detects the system voltage, which takes the guesswork out of setup and ensures efficient charging. For someone who relies on solar power to keep all my gear running when camping, this is perfect.The LCD display is clear and informative, providing all the essential data at a glance. You can monitor the charging status, battery voltage, and load status without any hassle. It’s like having a mini command center for your power needs, which is crucial when you’re out in the wild.The 10A capacity is robust enough for most small to medium solar setups. I’ve been using it to manage a solar panel array that powers my essential gear, and it hasn’t let me down. It regulates the charge perfectly, ensuring my batteries are always at optimal levels.One of the standout features is the ease of installation. Even in the middle of nowhere, I had this controller up and running in no time. The user manual is straightforward, and the setup process is intuitive, which is a relief when you’re dealing with complex off-grid systems.The build quality is impressive. It feels rugged and durable, which gives me confidence that it can withstand the harsh conditions of outdoor use. It’s not just a piece of tech; it’s a survival tool that I can rely on.Overall, I’m really happy with this nifty little device. It’s a reliable, versatile, and efficient solution for managing solar power in off-grid scenarios. If you’re a survivalist looking to keep your gear powered and ready, I highly recommend giving this controller a try. It’s going to be an indispensable part of my off-grid setup!

This is the PWM 10 amp charge controller.While it is plastic, it feels solid and sturdy, not light and flimsy as one or 2 others we have tried from generic makers.PWM means it uses Pulse width modulation to regulate the flow.This is not as efficient as an MPPT but it is cheaper usually to go with this kind and if you just want a controller to keep your 12v or 24 volt battery or gadgets from being overloaded, this will do it .The instructions feel a bit rushed.Spelling mistakes etc and the paper and print quality makes it feel more a leaflet than a manual.Most likely to keep costs down.Add you battery before the panel for safety.They suggest installing a fuse between the battery and the controller.You get 6 fork connectors to crimp to your in and out wires.The terminals are screw down type and you just lift the flap to secure them with a screw driver.Easy.You don't have to have a load.There are 2 times 5v 2 amp usbs which can be used when its all wired up.Various button presses to cycle through the options which are laid out in the instructions and really need it in front of you are you work through it.You can screw the controller to a wall or wooden support using the 4 fixing holes.Seems worth the asking price of around £18This is going in the workshop to charge a small 12v batt for running a diesel heater and making use of the usb outputs for small tool charging.They do various videos of their earlier models online.

Yes, this device does work and delivers. But trying to understand the instructions was a bit of a challenge hence the four star rating. The Newpowa website does have the PDF file in which anyone can download since the booklet is small and not easy to read.

I'm using this on a DIY 120AH lithium battery box. I needed a controller that would fit in a limited space and this unit worked perfectly both in size and operating parameters. Most of the time it's connected to a 160W vehicle rooftop panel, but I also charge it with a 320W solar suitcase with ~42v/10amp output, so it's a perfect match for this controller. I've been using this for almost a year and I am very pleased.

Upgraded to this 150v unit from the 100v tracer 4210AN. Should've went with the 150v to start with. It's working good.. I'm happy with it.. 😁note; page 10 of tracer4215BN manual states "when PV modules are connected in series, the open circuit voltage of PV array must Not exceed 138v (25°c). 150v @ min temp.

I didn't use it, I returned it because I was building a 48 volt system and didn't catch this would not work for 48 v.I am using Newpowa solar panels, the 12 v 210 watt units, and with a potential of 1680 watts full sun for 8, I got 1655 watts to the charge controller, near perfect even thru 80 feet of cable.
