Automatic Transfer Switch For Offgrid Solar
(I make a commission for purchases made through the links below)
If you have an off-grid solar power system AND grid power, use this switch to power your devices until the solar battery is low, then it will switch to grid power. This is a great switch to use if you have a stationary RV and wish to use both solar power and grid power. You can also program the cut-off voltage (the battery voltage when it switches to grid power), so that your batteries last a long time. You can also program the reconnect voltage as well.
Very easy to setup! Run some extension cords to the terminals and plug it into your system. It will turn on when you connect your solar battery to the terminals. It can work with 12/24/48 volt solar power systems

About this item
【Beneficial to Solar or Wind System】: On cloudy or windless days when your battery gets low, it will automatically switch to grid power, protect your battery.
【Works like an opposite direction UPS】: The ATS controller will switch to grid power when batteries votagle are lower than cut off point,it will switch back to battery power when the batteries votagle are higher than recovery point.
【Auto distinguish】: DC 12/24/48V,AC 100-120V 60HZ / 220-240V 50HZ auto distinguish.User can define the Cut-Off and Recovery Voltages.Recovery voltage must be higher than Cut-off voltage. Battery type: Suitable for Sealed,Gel,Lead-acid,Lithium battery and so on. as long as the voltage of your battery are within the voltage ranges in the followings.9-17V at 12V system;18-30V at 24V system; 30-60V at 48V system.
【Big Power】: 5.5kw(110V) or 11KW(220v),Fast Transfer time:Inverter transfer to public power ≤10ms,public power transfer to inverter ≤16ms. 【LCD display】: Battery real-time voltage;working status of public power,inverter and battery.⭐Note: The controller needs to connect the battery, powered by the battery and get battery power data.
Automatic Transfer Switch For Generator/Shore Power/Inverter (2 Inputs Only) For RV's
Not as sophisticated or dedicated to solar as the last one, but you can hook up multiple inputs. Lots of options here!
- Can handle 2 sources of 30 amps at one time
- Made for use with inverter, shore power or generators
- Delay switch for use with generators
- Comes with knockouts for easy and professional installation
- Single relay
Functions and Features: 100a 2p dual power auto transfer switch W2R is a PC-level infrequent switching switch, mainly used for automatic or manual conversion of two power supplies, and can test whether the common power supply or backup power supply is normal. When the common power supply A is abnormal, the backup power supply B is quickly switched and put into use within 0.05 seconds to ensure the continuity, reliability and safety of power supply. When the common power supply returns to normal, it automatically switches from the backup power supply to the common power supply. Both power supply A and power supply B can be connected to the mains/generator/photovoltaic, with four wiring
Wide Application: This 2P dual power ATS ensures a stable power supply, it is used in situations where power outages cannot be sustained,which is very suitable for high-demand equipment; used in hospitals, low-temperature cold storage, data centers and emergency systems, it can automatically and quickly switch to the backup power supply during the power outage of the main power supply to ensure safe and reliable power supply. Suitable for indoor and outdoor generators
