Solar Epic is a company that is destined to deliver quality to the customers. They have their tagline and slogan as “great solar great future”. They are offering affordable solar products and solar panels accessories. They also offer quality power inverters. Their products can be found in amazon just like this particular solar charge controller.
As we all say there is no solar energy system that can work without a charge controller. Whether it is off grid or it is a grid connected. In off-grid solar systems solar charge controller have various uses;
- They contain diodes in their circuit which blocks the flow back of current to the solar panels
- They also stabilise the amount of current that is flowing into the battery.
- solar charge controllers provide power outlets for dc loads.
For our solar charge controller, SolarEpic MPPT 40A Solar Charge Controller 150V PV input, for us to say it is good, it has all these functions you need. And furthermore, it is an MPPT(Maximum Power Point Tracker) type of solar charge controller.
This means that the solar charge controller tracks the solar panel highest power point and ensure high power transfer to the battery. That way efficiency is ensured.
Why SolarEpic MPPT 40A Solar Charge Controller 150V PV input?
- The Tracer-BN series controller is for the off-grid solar system and control the charging and discharging of the battery.
- The controller features a smart tracking algorithm that maximises the energy from the solar PV module(s) and charges the battery.
- At the same time, the low voltage disconnect function (LVD) will prevent the battery from over-discharging.
- The battery charging process has been optimised for long battery life and improved system performance.
- The comprehensive self-diagnostics and electronic protection functions can prevent damage from installation mistakes or system faults.
- In addition, the Tracer-BN series controller has an RJ45 interface to allow communication with other accessories.

Hope you found this Review on this 40A solar charge controller to be helpful, Always research a Product before you go and buy it. Also, make sure to look through all of our other reviews on controllers as we make new reviews all the time.
mike collins says
with a 12v battery bank, how many 100w panels can i put on this charge controller?
Our solar PV technician will answer this question tommorow as he is more qualified,
Hi Mike Collins, thank you for your inquiries.
1. When you have a 12v Battery bank, you will automatically use the solar charge controller on the 12v modes.
2. While in this 12v mode you will have to make sure that the solar array output also gives out 12v to the solar charge controller.
3. We know that when solar panels are connected in series, the total voltage will add up and current will be the same as for one solar panel (SO THIS won’t WORK FOR US)
So to answer your question you will need to connect the solar panels in parallel so that the voltage remains the same as for one solar panel(which is the voltage required for our charge controller) and now current adds up.
Check the solar panels specific current rating, and divide with 40A to see how many the charge controller can hold.
Hope I answered your question, thank you and more enquires are welcomed.
