OK I'm a noob so I bought 5 panels 456w in series
A powmr 8.2 240v which is what I needed and wanted and a e-box 48100r for batteries all hooked up the batteries were used once and now the inverter is flashing BP I have a 48 volt charger I put on it starts to charge after a while it starts to beep and the error light comes on I can't get (according to my meter ) more than 41 volt I'm so confused everything is brand new please help
Thanks in advance

?I have so much to learn

Per the manual "bP" means the battery isn't connected.

Did you follow the soft start procedure in the battery manual?

Simply connecting the inverter to the battery may trigger short circuit protection due to surge when charging the capacitors. It will disable the battery.

 

[davehall]

Yes I did it did recognize the battery once then BP came up I checked the voltage it was low so I charged it with a 48v charger as per distributor and it comes up as BP

It says it's charged as per the lights

That's what I get

What is battery voltage right now measured with a separate voltmeter at the battery terminals?

What is battery voltage right now measured with a separate voltmeter at the battery terminals?

So when the inverter is on it reads 7.1
At the battery it's self not connected it's 41

So when the inverter is on it reads 7.1
At the battery it's self not connected it's 41

7.1 indicates BMS protection - either low voltage or short circuit protection.

Your battery is completely EMPTY.

Completely disconnect the inverter from the battery.

Charge the battery until it is at least 52.8V... preferably 55.2V

When I put the charger on it takes 4 ever to charge it and then after a while it screams at me with the prote tion alarm

When I put the battery on charge after a while I get the alarm and red light

 

[sunshine_eggo]

That doesn't change anything. Charge to at least 52.8V, preferably 55.2V.

Then connect and start according to the battery directions.

OK now should I shut down the battery or leave it on if it's on it screams at me

 

[davehall]

And the red light comes on

 

[davehall]

And the red light comes on

Also I have mains coming in to it as well shouldn't that charge it when it's hooked in to the battery

 

[400bird]

When I put the charger on it takes 4 ever to charge it

What's 4 ever in hours? How many amps does your charger output? You've got a 100 amp-hour battery, so a 5 amp charger would take 20 hours to charge.

 

[davehall]

Also I have mains coming in to it as well shouldn't that charge it when it's hooked in to the battery

Also I have a outlet for 120 and 240 so the charger I have in the 120 it didn't Come with a manual
