My invertor drained my battery to the point that the solar system can't wake it. How do I "wake it up" Even trickle chargers are not helping. Can I use my vehicle to jump start it?

Hello, Do you have a multi-meter to test the voltage on the the battery? Prior to draining did the inverter give any warning lights or alarms? -Renogy Team

Why do you think the inverter did it? How large is your inverter? What kind of draw do you have hooked to your inverter? How large and what kind of battery do you have? How old is your battery?
WAY MORE INFO IS needed to help you.....
No don't hook your car to it.... That won't jump start your battery it sounds like it's dead to me...

Hi Admin, do your Li batteries have sleep or standby circuitry?

Hi Admin, do your Li batteries have sleep or standby circuitry? I don't know. Renogy 100AMP HR L.I. with a management system built in.

Well if it does maybe Admin will let us know and suggest a way to boost it into taking a charge, getting it out of standby/sleep mode. Was a temperature sense used? The Rover MPPT charge controller has a reactivation feature to awaken a sleeping lithium battery. The protection circuit of lithium battery will typically turn the battery off and make it unusable if over-discharged. This can happen when storing a lithium battery pack in a discharged state for any length of time as self-discharge would gradually deplete the remaining charge. Without the wake-up feature to reactivate and recharge batteries, these batteries would become unserviceable and the packs would be discarded. The Rover will apply a small charge current to activate the protection circuit and if a correct cell voltage can be reached, it starts a normal charge. -Renogy Team

It should be for all Rover-Li. However, some Rovers might still be in circulation through distributors without the Li mark. -Renogy Team

Okay, now how do I wake it up. Do I hook up the Rover and wait? It was hooked up for half a day before I discovered the problem, so I disconnected it, then hooked it back up after trying to use a trickle charger. Rover still said ACR, and never got the system going.

Rover still said ACR, and never got the system going. What kind of trickle charger did you use for the LFP battery? We would recommend to disconnect all loads first and have the Rover connected, it should be an automatic process. -Renogy Team

I hooked it back to the Rover and the system (200 Watt Renogy) , All ofwhich I bought a few months ago. I have no loads on the Rover, or the battery. I left it for 10 mins. and the Rover still Had ACR on the screen. Do I leave it longer, or is there a way to program the Rover. It did not respond to pushing any of the buttons.

If you have not connected a temperature sensor while having the LFP battery connected or have not incorrectly trickle charged the battery on your own, then we would recommend you call Renogy Technical Support to determine whether the controller is defective since it has the ACr code. They will be asking similar questions to this forum, for example what kind of multi-meter readings are you getting. -Renogy Team
