Electric valve solar power supply system
In reviewing energy requirements first, a typical remote valve actuator site will have some sort of communication, whether it's licensed radio, cellular, or satellite. This same site will likely have a small PLC or SCADA system. In the event of a power failure, several days of UPS backup power is desirable – enough time. The instantaneous power required by a valve actuator depends on the application. Electric motors from less than 1 horsepower to several 10's of horsepower are. The power requirements of a remote actuator system are an entirely different matter; especially where standard AC motors drive the actuator. AC motors, whether. Depending on the size of the valve and the stroke time required, there are alternatives to consider. Several manufacturers of actuators offer 24/48 Volt DC powered. The voltage of the actuator motor is also an issue. The industry habit is to specify 480 Volt 3-phase motors. In the case of Solarcraft's inverter, 120/240 single/split phase.

Solar powered and line powered UPS systems can provide both the power and reliability to remotely operate a valve when the need arises. Solarcraft engineers and fabricates complete systems, including a communication device, PLC or SCADA system, and the actuator, to operate critical shutdown valves and valve actuators in remote areas.
Can solar power be used for valve actuation?
An important factor when considering solar power for valve actuation applications is the potential for leaks. If the equipment is not properly designed for the environment, operating conditions, and pressure and temperature cycling, hydraulic systems can leak. In addition, the fluid itself needs attention.
How does a solar-powered valve actuator work?
The hydraulic pressure is used to hold the valve open and compress a powerful, self-contained spring. If valve closure is required, hydraulic pressure is released and the spring quickly closes the valve, preventing further loss of product. These are just two examples of the hundreds of viable applications for solar-powered valve actuators.
How many solar-powered actuators have been installed on a pipeline?
In northern Argentina, 39 solar-powered actuators were field installed on an existing 24-inch product pipeline's through-conduit gate valves. The actuators were installed along with a new pipeline SCADA system, which allows the pipeline dispatcher to monitor pressures and flow at each valve site and close sectional block valves if needed.
How can solar electric battery storage and hydraulic accumulator storage help?
High speed, high force and critical control, which are all necessary requirements for dependable valve actuator operation, can be accomplished with an appropriate hydraulic operating system. By combining solar electric battery storage with hydraulic accumulator storage, very high operating forces and flexible speed control are possible.
How does a solar-powered spring return rotary actuator work?
In this application, a solar-powered spring return rotary actuator permits remote shutoff of a critical products pipeline if damage occurs from barge traffic or heavy rains. Solar electrical energy is used to generate hydraulic pressure. The hydraulic pressure is used to hold the valve open and compress a powerful, self-contained spring.

2 solar panels to charge the electric cabinet
When you want to connect two solar panels to one battery, you must first connect your battery to the charge controller. It is crucial that you do this step first. If you connect the solar panels to the charge controller, you might risk destroying the charge controller in the process. Wire thickness depends on your charge. In this step, you will learn how to connect two solar panels. This can be done in series or in parallel. I have written an article about the pros and cons of both of them. You can read it here:. The wire from the solar panel will be too short to run to your charge controller. Use this wireto extend it so it can reach your charge controller. Most of the time, you are going to use the series. If you have small DC loads, you can connect them to the load terminal on the charge controller. I recommend using the battery terminals if you want to use an inverter. See the following.

How to charge multiple batteries with a solar charge controller?
With most solar charge controllers, you can only charge one battery. So, you need to know how to charge multiple batteries with one solar panel. Some charge controllers now have an added option of having two battery banks. You charge the two banks separately using the same solar panels and the same controller.
Can I charge two solar panels separately?
You charge the two banks separately using the same solar panels and the same controller. You should also find out what batteries to use for your solar panels. You can use multiple charge controllers if the charging current of your solar array is more than the current of your charge controller.
Can you connect solar panels directly to a battery?
First of all, you should know this: You cannot connect your solar panels directly to a battery. When you connect your solar panels directly to your battery, you will damage the battery (lead-acid or lithium). You need a device that measures the state of charge of your battery and charges it accordingly, just like a car battery charger.
What happens if you connect solar panels directly to a battery?
When you connect your solar panels directly to your battery, you will damage the battery (lead-acid or lithium). You need a device that measures the state of charge of your battery and charges it accordingly, just like a car battery charger. The device we are going to use is called a charge controller.
How many solar panels can I connect to my charge controller?
The amount of solar panels you can connect to your charge controller depends on the power output of your charge controller. This is usually written on the sales page of the charge controller you will buy. If your battery bank voltage is higher, then you can attach more solar panels to it. We can see this in the datasheet for the EPever Tracer: Max.
