I put my first portable system together almost two years ago using a 100Ah 12V Lifepo4 prismatic cell battery from Shenzhen Delong Energy, a Samlex PST-600 12v 600W pure sine inverter from Don Rowe, a Renogy Wanderer Li 30A 12V PWM charge controller (Max. PV Input Power: 400W), SAE Socket Port for solar input wires, and a Bayite DC 6.5-100V 0-100A Multimeter to track solar charging. I later added a AiLi Voltmeter Ammeter Current Meter 8-80V 0-100A to monitor battery levels. I mostly charge it using 2 or 3 100W panels and use it to power things in my workshop. It has been a fun learning experience. Thanks to all on this forum for sharing their experiences!
