Human Generator Systems To Charge A Solar Generator Power Station
A popular idea is to use a pedal power bike generator system to generate electric power and use it to charge a battery or solar generator also known as a portable power station. The problem is that only expensive systems will handle high voltage from the bike generator system. If you want the cheapest solution then you will need to use an over voltage protection relay module with an inexensive power station such as the $129 Flashfish shown below. .
This over votlage protection relay will open up the connection between the bike generator and the solar generator whenever you start to pedal too fast and exceed the max voltage of your solar generator.
The schematic wiring diagram shows how to wire the unit up for over Voltage protection. The capacitor should be rated at least at 5000uF 25V.
You may ask why this diagram does not have a blocking diode. Solar generators already have a built in blocking diode so you don’t need one. The only reason why you would need one is to charge a battery.
For example I purchased the FlashFish 200W for $129.00. It is a tiny little solar generator power station that works great and it has a lot of power for such a small size. We blew it up (AKA “let the magic smoke out ” ) when we used it with a 48V DC bike generator. The specifications for this Flashfish solar generator state that it is able to take a max input charge voltage of 24V DC. A great solution to protect it from being damaged by the bike generator is to install a NC25A-12V unit which opens up the relay connection at about 16V DC. This means the voltage going into the FlashFish will never go over 16V DC. It will be protected from damage from high Voltage from pedaling on the bike generator too fast.
When you are pedaling you will feel when the relay opens up because the bike generator will suddenly get really easy to pedal. This will teach you what pace to pedal at so you will develop an instinct as to how fast to pedal to keep your bicycle generator output below 16V DC.
NOTE: The reason why the NC25A is so special is that it can handle a maximum input Voltage of 140V DC. When the NC25A opens up its relay contacts at 16VDC the built in voltage monitoring circuit then sees a BIG votlage spike from the bike generator. Most over voltage protection relay modules only go to 48DC max input voltage so they get destroyed. This is not the case for the NC25A.
Solar / Bike Generator Hybrid Mode
You may want to be able to use a solar panel with the solar generator. The key is to use a connector adapter that allows you to switch back and forth between the bike gneerator . If you want the ability to use them at the same time then contact us and we will give you a diagram on how to do that.
Contact us now for help picking out your off grid battery charging system. We have DIY kits that allow you to save money by putting the pedal power generator system together yourself. Or you can purchase the system fully assembled. Text or call us now at 971-281-0685. One of the most popular portable battery power stations today is made by a company called “Bluetti” . This is shown in ithe photo above. Model: AC200MAX.

1300W Max. Fast Dual Charging (Solar + AC Adapter)
Smart Control & Monitor in BLUETTI App
This model accepts an input charge Voltage (aka VOC) of 10 Volts DC up to 150 Volts DC. note: Because this model has such a high input charging Voltage limit of 150V it is not necessary to install an Over Voltage potection module because the bike generator will not put out more than 150V DC. We can give you wire adapter to connect the PPG-R500 to the Bluetti AC200MAX. You can see this power station HERE https://amzn.to/38Gkc7h. We can also give you some lower cost options.
Another more cheap portable power station is the flashfish.
This unit is very affordable and works very well to store your energy from your pedal power generator system. This unit has a max allowable charge Voltage of 24V. Because of this max limit a bike generator system must have Over Voltage protection such that the Voltage never goes over 24V which would damage the portabl power station.

This interactive display provides children with the unique experience of generating electricity and then selecting which appliances in the home to power up. The hair drier and blender are the most difficult item giving the children a very high resistance to work against.
