My AGM batteries are dying [2 of the 4 go down to 10V before system shuts down]. I have ordered new Lithium-Ions but it will be a week before they get here. Whenever I put a heavy load on, even when the sun is shining brightly [hair dryer or kettle] the inverter shows a huge load spike [more than double the rated load], turns off, and shows a #6 Fault - Output Voltage is Abnormal.

Is this normal 🙂?

Anything I can do about it [in addition or instead of not using the heavy load items]?

My current and very small Off-The-Grid system:

• Mecer SOL-I-AX-3MPlus48 Inverter/Charger
• 6-300W Enersol panels X 4hrs=3600Wh[Watt hours] X.8=5760Wh power potential per day
• 4-12V 100amp/hour Vision batteries hooked in series=4800Wh storage potential [2400Wh at 50% SOC]
• Yamaha EF5500FW Generator

I don't think so. But I also have no suggestions, sorry. Hopefully with the lithium batteries, it will stop doing that.
