@jp – the charger relationship doesn’t quite work that way. The 5V 2.0A is typically the stated maximum the charger can supply – however for the battery charger circuit there are limitations. I use a USB Meter to determine what is actually going on.

The Mayfly 1.x charger circuit is to 0.5A as default  but can be changed to 1.0A. I always change…[Read more]

(previous post deleted and restated)    @jp – interesting data. It very much looks like up to early October the solar was delivering enough power for the system.

Then with the seasons solar changing, the solar panel aspect is not delivering the power needed

What I would recommend is a) need to charge up the internal LiIon 4.4Ahr battery

1. …

@jp – interesting data. It very much looks like its the solar panel aspect that is not delivering the power with the seasons changing, and some loss of solar.  a) So anything you can do to help out a better solar aspect  – less shade would help, and  solar panels are best set at an optimal 120 from horizontal for that location (h…[Read more]

Hi @jp – I only install 2.5W or for a shady location I upgrade to 10W.   Can you share the site that is publishing on, and can see how fast the power went down.

The non recharge batteries could work – but you need to do a lot more power calculations to understand how long they will work.  4 batteries (4*1.6V =6V) will work for a boost plugged in…[Read more]

@jp  thanks for sharing – power is a challenge when there isn’t enough of it. Finding enough power for your systems is the easiest step, – that is upsizing the solar panels, and ensuring they have enough solar aspect this time of year.

Just wondering, what is the standard kit that you have and source- sounds like you have the Mayfly 1.1 – what…[Read more]
