HQST Solar control’s the manufacturing process of our own solar modules which gives us many advantages, arguably the biggest one being able to control the quality of all of our units. This allows us to ensure that for every panel we produce, we are there every step of the way.

HQST Solar specializes in off-grid applications so our products are tailored towards cabins, RVs, boats, and anything else off of the grid. We believe that off-grid gives you the freedom to generate energy wherever you want as long as the sun is shining. All this energy can be stored in a battery bank, which can be accessed at any time, to provide you with power to run any DC appliance, or AC if you have a power inverter.

HQST Solar has a very user-friendly DIY approach to solar. We like to provide all of the components that you need to set up an off-grid system along with providing you with instructions on how to set up your solar array. This allows you to essentially learn as you go and develop a strong understanding of solar.

We also offer an OEM service for companies looking to customize their own panel via wattage, size, cell type, etc.

HQST MPPT Charge Controller applied Advanced Maximum Power Point Tracking (MPPT) technology to help regulate the power from your solar panel to battery with efficiency no less than 99.5%. This 20/30/40 Amp MPPT solar regulator adopts high-quality components with a maximum conversion efficiency of 98%. The MPPT battery charging can greatly increase the lifetime of your battery and has various unique functions and quite easy to use features.

With MPPT control algorithm, in any situation, products of this series can fast and accurately track out the best maximum power point (MPP) of a photovoltaic array to obtain the maximum solar energy in time, which remarkably improves energy efficiency. There is dual display function: local LCD panel and remote meter. With Modbus communication protocol interface, it is convenient for customers to expand applications and monitor in various fields like telecommunication base station, household system, street lighting system, wilderness monitoring system, etc. All-round electronic fault self-test function and enhanced electronic protection function could furthest avoid damages on system components resulting from
