The Axial turbine is for low head power plants. Water flows axially into and out of the turbine. Axial flow turbines fall into two categories, fixed blade runner and variable pitch runner, also known as a Kaplan turbine. Fixed blade turbines are very well suited to low head power plants with limited variation in head and load. Its main advantage is its simple design. When operated at fixed speed, maximum efficiency is achieved at the design head and water flow. Kaplan turbines are used for medium to large power stations where there are large variations in the head, water flow and load. Its main advantage is its ability to adapt to variable conditions with a high efficiency. The variable pitch runner is mechanically more complex than a fixed pitch runner. Axial flow turbines can be supplied for a head of 2m to 70 m. The runner diameter is available from 0.6 m to 5 m. Power capacity is from 55 kW to 50 MW.

With the features of PWM (Pulse Width Modulation) battery charging and unique control technology, the PV charge controller improves battery life efficiently. The PV charge controller is only suitable for controlling solar modules. Never connect any other types of charging source to the controller. This can destroy the controller and/or the charging source permanently. To meet different solar power stations need, there are 48V 96V 120V192V 220V 240V 360V 384V 480V 492V and 600V other normal series voltage level base on different battery voltage of off-grid PV power station system project. Product Feature: 1, The solar controller uses high performance 32-bit chips which is excellent EMC design 2, The controller adopts advanced PID algorithm which has more accurate battery energy management system to improve the battery efficiency 45% at least 3, The controller adopts three charging stages (buck charging, equalize charging and float charging) which can maximize the utilization of photovoltaic modules and batteries 4, IGBT Modular design ensure stable and efficiency performance of solar controller and solar power system 5, The controller has perfect battery protection function and with multi-stage charging technology to improve battery life 35% at least 6, The controller has double loop control function of voltage loop and current loop, user can set the limiting charging current 7, Fully enclosed duct design and high-speed fan for cooling makes the controller working under harsh environments 8, The controller has power generation statistics and real-time power curve function, so we can know power generating information at any time 9, Colorful LCD display, touching key and multi-language option makes the HMC (Human Machine communication) easy and convenient. Users also can set working parameters through the LCD panel and touching keys according to different battery feature 10, The controller also has temperature compensation function and RTC real time clock function, 11, Standard Modbus protocol for RS-485 or GPRS communication to extend the communication distance (optional function) 12, The patent of second protection function which can protect battery from over charging due to power switch failure (optional function)
