In real life, you can connect your cellphone with the speaker, headset, etc., by blue tooth device. Especially Iphone wirless blue tooth Airpods are very popular in the world, also Huawei Freebuds are very strong in China and other countries, maybe you are using blue tooth function every day. For solar charging systems, you can also have blue tooth function now. You can check the solar system conditions with your cellphone, it looks amazing. Lumiax now begins to release its new model with blue tooth function: MT3075 BT.
Here we will introduce some functions:
1. First it is 30A MPPT. Charging and discharging current are both 30A, at temperature of 25 celsius degree. It can charge and discharging 100% at same time, and work very stable, no overheating. This is very important for good quality and long time life span.
2. With high tracking efficiency, can reach to 99.9%. and it can stay at the max power point very stable, not like some bad quality MPPT, which always sways to the left and right around the max power point. You can test this by one MPPT simulation equipment.
3. With high conversion efficiency, can reach to 98%. Now even the top brand MPPT controllers in the world only mark this in the specs. Some customers have tested the conversion efficiency and are very satisfied with that.
4. Now come to the point about blue tooth function. You can install the APP in your Android cellphone(IOS in the future), then you can connect your cellphone with MT3075 BT, and you will know all the information of the solar system. Like the specs of solar panel, battery, and load. You will know how many ampere current comes from the panel, what is the battery highest voltage and lowest voltage, what is the load current, and all the data in 60 days. Here are some pictures from my cellphone.

5. The most important function is that you can use blue tooth to choose controller type, to charge lead acid battery or lithium battery. Before some retailers have to do the stock of both lead acid battery solar controllers and lithium battery controllers at the same time, some even stock more lithium battery controllers, because of different lithium battery types and voltage. That will increase financial pressure on the retailers and distributors. Now just one model of MT3075 BT, can be set to lead acid battery controllers or lithium battery controllers by the user’s cellphone, which can reduce half of the stock, even more.
6. If there is something wrong, you can judge the reason very easily, like low voltage disconnect because of rainy days, you can know it very easily from the panel information and battery information. If you don’t know you can send the pictures to some technical guys to judge for you.
7. MT3075 BT are very suitable for RV and boats, which require more advanced function, and easy to operate. Some European companies are expecting to sell this blue tooth version MPPT solar controllers this year. Now it comes.
