DIY 576 watt hour Portable Solar Power Generator

Hello Everyone
In this video we are building a 576wh #portable #solar #generator for off grid or grid down power. This kind of solar generator is useful for many renewable power applications. Once build and put in to use, it generates 100% free energy for emergency power, communications, amateur radio, boondocking, van or RV life, to keep food or meficine refrigerated during grid down emergencies.

Main features
– 576 watt hours, 45amp hours
– 2000 charge cycles
– 30A ports
– 2x USB ports
– Internal Bluetooth battery monitor
– 4x DC Powerpole ports
– Every port is individually fused
– MPPT charge controller
– Dual Solar inputs
– Total weight 18lbs (8.3kg)
– Easy maintenance
– Replaceable Components
– Optional pure sinewave inverter
– Easy to build

The closest commercial product is the Goal Zero Yeti 400 Lithium. Our diy solar power generator will outperform the Yeti Lithium, (unless you need an inverter), the Yeti has one built in, but an onverter is optional in the DIY Solar Generator . Most people don’t need AC power or the inverter with a solar generator. They just need tthe right connectors for their gear.

An interesting feature on the solar generator is the wireless battery monitor from Thornwave labs. The battery monitor is a Bluetooth enabled shunt using Bluetooth SE to send information about the state of the system straight to our mobile phone. it’s also got an API to get data out to something like a raspberry pi or arduino for data logging.
