Do I need to isolate the controller from the battery when using an inverter that is connected directly to the battery? My controller is a cheapo 10A 12v so I am assuming it'll overload the controllers 'load' output.

Do I need to consider vibration or shock loading for a small system in a bicycle trailer?

1. Should panels always be under load is or no connection no flow of current (i.e isolated on a DP switch). 2. Fire risk. Plenty of vehicles go up in smoke. What's the risk with a PV setup? 3. Cheapass alibaba 3.2v cells. Buy or avoid?

Question: how do you determine when a LiFePo battery is in need of a recharge? If you look at the following Pb acid .V. lifepo DoD graph: https://www.thepilotgroup.co.uk/lithium-ion-battery-vs-lead-acid-battery/ it's reasonably easy to infer when the lead batt could do with a recharge. Do...

I watched this video: He suggests that trickle charging is bad but doesn't explain why. So I googled: lifepo4 trickle charge issues and got this...

If I have some thin wire and I want it to handle more current can I simply get three lengths, trim the sheath off at the ends and twist the bare wire together at the ends to 'make one thicker wire'?? Or doesn't it work that way?

I know it is theoretically possible but has anyone actually hooked up a pv system to an electric vehicle?

I have the most basic 12v/10a kit from ecopower/solar or whatever they are called. I have a 600W inverter connected directly to my battery (through a shunt). This will charge my ebike battery which, while not the kits intended purpose, is one of mine. I was advised to totally isolate the charge...

Looking forward, is there a shunt/meter combo that I can use as I upgrade/scale up a system? I currently have the 12V10A/25W system from Ecosomething. Sooner or later I will assembly a 24V system with proper batteries to service higher loads. Does a 'load measuring' device exist that can, for...
