Hey,
We recently had our Zamp 10 amp controller fail after 7 years. So, we ordered a replacement.
Just for fun I made a new harness and connected the controller to our new Bluetti 100 W solar panel. Comparing our smart shunt information with the new controller and the new Bluetti panel we were receiving the same amount of charge, if not 5-10% more than our original Zamp legacy 120 W suitcase unit.
Gone is our old 120 W 70 pound unit and hello our new smaller 100 W unit. Also, the controller can tuck into the back pocket of the solar panel with some reflective bubble foil backer to reduce heat build up from the panel.
New Zamp charging profiles compared to the older version and advanced solar panel technologies made the difference perhaps?
We like easy.
BTW Heavy forest fire smoke is reducing solar input.
Nice! Both the electronics and panel have advanced a lot since 2018. I'm not at all surprised at the increase in output, even with 20 W less of panel.
