Computer inverter to make an emergency home lighting

[sicetaitsimple]

This suspense is unbearable! Are you sending a message to 48V?

While eating, I failed tests.

Shutdown after 6:15 a.m., and 730 Wh of drawdown, stopped at 43.9V, it yelled.

So pretty encouraging, after that.

We'll see, after a night of charging, what happens.

There, it begins to be reasonable.

I don't think I'll get much more, but I have to test, at around 500W of consumption.

Oh no, that's not serious!

Well, yes, it happens to me several times a day.

Welcome to the Phil59Show.

The batteries, l), after disconnection, are at more than 50V.

They would still have supported a little more, probably 1 kWh, including the inverter

Afterwards I will also have the 4X10S to put in //, and I could say that I am able to have lighting at night, and probably box, and main tv.

New test today, with radiator, about 550W peak, about 300 Wh consumption over 1H, before it cuts wildly.

Only 300Wh of consumption, because in fact a radiator cuts off when it arrives at TP, and re-heats afterwards.

But hey, it still holds up with 550W peak consumption, I shouldn't come to that.

After these tests, I left the batteries to rest.

One is just over 48V, and the other 50V.

I plugged them into the inverter, so it charges a little, I know it takes a long time on the inverter, but there, after 3 hours, not even 0.1V more.

Someone would have any idea ?

strangely the same cells coming from the same supplier as you did not make much use on my Matra bike...

[phil59]

Well, with the 48V chargers that Chevreuse/Alain gave me, they charge well.

They are no longer first youths, but they turn.

I wonder rather, if it is not the voltages of load of the inverter which do not go, or the charger part of the inverter HS?

Yes, charging recycling batteries with a recycling inverter is certainly not the best way to see clearly.
