I have a 200 ah battery hooked up to solar via an inverter. can i use this when sun isn’t shining? do i need to disconnect from the inverter?

Hi I’ve had mine a few months and it’s very good. I use it to keep two separate banks of two x 120ah batteries topped up when my solar isn’t enough. I plug it into the 240 electric and fasten it onto my inverter. My batteries were often going flat, they are always full now. This item also has the ability to bring dead batteries back to life it is an amazing product. There are also loads of accessories available to buy so that you can use it for other things. It charged my car battery up beautifully yesterday. I wish I’d had this years ago it’s well worth the money

Will supply mode supply constant 10a with the battery connected? need it for flashing ecu

It depends if tuning the ECU requires applying a "load" (e.g., turning on lights) during reprogramming. If yes, then it's not sufficient. If no, then using the 12V Supply Mode should work, but remember not to add any loads during the process. It is also best practice to contact the manufacturer to make sure the vehicle does not draw more than 10-amps during reprogramming.

Can I charge my iphone

For phones and other USB charged devices buy the NOCO Boost Sport or similar unit which is a combined 12v jump starter, USB supply/charger and 5 mode LED emergency torch designed to be kept in the vehicle. For camping/day trips it can be recharged with a small solar panel or from a vehicle socket as it has standard USB input and outputs.

Live in a flat so my car is always parked in street or in a public car park so can't plug in to mains/connect to battery in car at same time. Suitable

You can remove the battery and charge it in your flat
