Temporary battery suggestions

Hi I'm designing a solar setup using 5kw of solar and a multiplus ii.

I have the multiplus, charge controler and panels etc coming next week. However battery is on order and will be minium of 2months.


Is there a cheap temporary battery anyone suggests. 48v....

What's the minium requirement for multiplus to function. Could I get 4 tiny 12v batteries and use them in series temporarily?

And if so any suggestions or will I just have to be patient and sit with panels in the garage not generating?

Thanks Matt

If you really want to use the system you need a battery that is not to small because it must be able to deliver short inrush currents.

So it depends on what you want to do with the setup.

I'm in the same situation, Victron equipment (MultiPlus II and SmartSolar MPPT) is delivered but the 48V 16s LiFePo4 battery is not ready yet. Is it possible to use a 55V power supply to mimic the battery for a few weeks?
