Starting in the am and continuing throughout the day, the inverter will randomly shut down, as if someone pushed the off switch. No warning, no errors, it just goes off. It can be immediately restarted and will run fine for a while before going off again.
What happens if the inverter is left on?
But either way it's not surprising that your battery is low by the next weekend if the inverter is left on. Check your inverter manual or data sheet for something like a "zero load power" or "idle load power" value in watts.
What happens if an inverter runs with low battery power?
If the inverter is on but unable to carry any load, the battery might be weak. Forcing an inverter to run with low battery power can be disastrous. An inverter that is connected to a battery bank depends on the battery for power. If the capacity is too low, the inverter will not be able to run its load. The solution is to charge the battery.
What happens if an inverter battery is dead?
An inverter is only as effective as its power source. If the battery is dead, the system will not run. Batteries can expire due to age, corrosion, damage, wear and tear etc. Before you buy a new one, do some checking to make sure the battery is indeed dead or defective.
Also note that a 2500W inverter on a 12V 100Ah battery only gives you less than 30 minutes of usage if you are using the full wattage and you drain the battery a full 100%. Most likely you are not using that much power but 100Ah of battery is really small for such a large inverter. And the larger an inverter the more they tend to drain at idle.
Why is my inverter not charging a battery?
An inverter that is connected to a battery bank depends on the battery for power. If the capacity is too low, the inverter will not be able to run its load. The solution is to charge the battery. If your system is on the grid, switch to AC power for now and let the battery get fully charged.
Can I use a solar inverter with a battery?
The caveat is that you must make sure you have enough loads to consume all solar power so it doesn't backfeed/damage the generator or connected electrical devices. Can you provide the full model number of your inverter. Many HD models are grid tied only with ZERO ability to be used with batteries.
