FAQ
1.How should I wire my panels with this MPPT charge controller?
Ensure the total Open Circuit Voltage (Voc) of your solar panels is within the 13V-60V input range. Panels can be wired in series or parallel to match this solar voltage window perfectly.
2.What are the advantages of Callsun's Boost MPPT technology?
Utilizing cutting-edge Pure Boost Topology, it delivers a peak 97% charging efficiency. It steps up low solar voltage (13V-60V) to charge high-voltage systems (24V-72V), maximizing energy for Golf Carts and EVs.
3.What is a Boost MPPT controller, and what batteries does it support?
Unlike standard controllers, a Boost MPPT tracks the maximum power point while raising lower solar voltage to charge higher-voltage batteries. With our One-Key Setup, it supports 24V to 72V Lithium, Lead-acid, GEL, and Flooded batteries.
4.Will this controller drain my vehicle's battery during long periods of inactivity?
No. It features Zero (0W) Standby Power Consumption because the system is powered directly by the solar panels rather than the battery bank. This protects your battery from drawing down during storage.

Product is good, does what it should. nice display, feels solid. Good shipping
So far this seems like a decent boost solar charge controller. The case is metal, which should hold up better than the plastic ones, and better dissipate heat. The unit is fairly compact. The controls and screen are decent. It seems to be working well so far, though I don't have the tools setup to fully monitor it to test efficiency. One end has common panel connectors pre-installed, while the other has a lever style wire connector. The only issue I noticed so far is that there are some nicks on the wire sheathing. The do not go that deep, but it is still a bit concerning to see. Overall this seems like a decent choice if you need to boost up 12V panels to work with systems of 24V - 72V.
I needed a solar charge controller that can charge my 24V LiFePO4 battery from a 12V solar panel. Most MPPT charge controllers are unable to charge a higher voltage battery from a solar panel that has a lower voltage. You'll need a step-up or boost MPPT solar charge controller like this. This Callsun Boost MPPT Solar Charge Controller is replacing a similar boost MPPT solar charge controller from another brand. This worst better and easier to set up.
Installing it was pretty easy since it came with MP4 connectors on the solar input side and level nut connectors on the battery side. Makes connection very quick and simple. I connected the battery first. However, the LCD screen didn't come on until I connected the solar panel. Just like my other Boost MPPT charge controller. Maybe it's to preserve battery?
I had to change the setting to the correct battery type. Setting it up for my correct battery type is fairly easy. Just press the setup button. Then select the battery type with the battery type button. Then cycle through the number of cells in series using the series button. That's it. It supports GEL, Li-ion, and LiFePO4 battery types. Supports a large range of voltages: 24V/36V/48V/60V/72V. Although for Li-ion, the lowest cell series is 7S. I have a 24V Li-ion battery that is 6S, but it is not common.
The LCD screen is easy to read. It is also backlit, so you can see it at night. The LCD screen seems to be on as long as there is solar input. The backlight comes on when you press a button and goes off after a few seconds to conserve energy. At $50, I think it's a good value for a Boost MPPT solar charge controller that supports a variety of voltages.
These are really simple to use if you know anything about solar.
This is especially good for charging your golf carts.
Most golf carts have 48v batteries so if you want to use your solar, you probably need this.
A smaller panel will only give you 20v so you need higher voltage to charge your battery.
This little nifty device solves your problem.
What I do is use a lighter flexible panel and glue it to the top of the golf cart.
Use this to slow charge the battery. Not a bad way to top off your golf cart batteries.
It starts at 24-volt batteries only. That was only noted obscurely. Not what I need. I'll be returning it, unused.
The solar charge regulator came in quickly and with no issues. The 15A 500W Boost MPPT Solar Charge Controller is a step-up voltage regulator for 24V/36V/48V/60V/72V lead-acid, LiFePO4 and lithium batteries. The leads from the batteries go to the quick connect on the regulator, then the other side gets connected to solar panels. This is an easy concept and easy to use. The regulator is accurate and extends battery life. The Callsun seems to be a good value for the money compared to others that I have used. This is ideal to use with golf carts, eBikes, and solar systems. I am happy with the regulator and would use again.
