Hi Christof,

We are working on the design of the battery so that it can “pass-through” the power from the panel to the output when current input exceeds 1.2A. It currently doesn’t do that though. The specs are a bit out of date, peak output is now 4.2A @ 19V. Jeff

Also your side https://www.voltaicsystems.com/powerfilm-battery.shtml is a great help. I will go for a V60.

One more question about a detail. It is mentioned that the V60’s peak current draw is about 1.2 A. Is this limit just for charging the battery or can the system forward more energy? My use-case would include powering a laptop at 19V with a 50w solar panel and the V60 to make sure I get a constant power supply. On sunny conditions the panel should be able to deliver more than 1.2A, can that passed through the system? After all the 19V output is rated with 3A.

Hi Christof,

The extra power gets dissipated as heat. Our AC chargers for the V60 are 2A. Here’s another example of this setup in action and reports are that it is working very well – http://www.outofedenwalk.com/blog/lab-talk/2013/04/harnessing-the-sun/

But I’m wondering: the input spec of the V60 say 14-20 V, 1.2 A. The 50W panel should be able to supply 2A in that voltage area. So is it real okay to use the battery? What is happening with the extra power of the panel.
