We've just installed a MultiPlus 3000/48 to run a pump Pedrollo 4SR6m/13 (https://www.arrosage-distribution.fr/pompe-4-sr-6m-13-pedrollo-6198.html). The pump is rated at 1500W, but seems to pull more like 2300W.
However the Color Control indicates that we're pulling 2877W from the battery, but only supplying 2277W to the pump. There is also a 148W dc load (the inverter?) So where is the 450W going?
Of course at 2900W the Multiplus gives me a overload warning, and after a half hour shuts off with an overtemp warning on the Color Control.
The only solution I've come up with for the moment is changing the Multiplus 3kw for a 5kW, but would hope to find another solution.
