# 24v vs 48v solar inverter

I have 4 batteries of 150AH each. Earlier these were connected as series to 48v solar inverter of 3000 Watts, now as that old inverter is dead and I need to replace it with new one. I want to know which inverter is better

24v Inverter with 4 batteries in parallel of 2
or
48v Inverter with 4 battereies in series


What are the benefits in term of charging time, backup etc

Note: 48v is costly as compare to 24v

• How many Watts is the inverter? – mkeith Jul 22 '16 at 19:04
• What voltage are your batteries? If they are 12V then you connect the 4 batteries in series to get 48V, and in series/parallel to get 24V. – Bruce Abbott Jul 22 '16 at 20:52
• @BruceAbbot Yes u r right, I updated the question – coure2011 Jul 23 '16 at 0:54
• @mkeith 3000 Watts – coure2011 Jul 23 '16 at 0:55
• Bruce Abbot's answer pretty much covers it. I agree 100% with him. And that is why I asked about the power rating. – mkeith Jul 23 '16 at 3:38
