 Hi every one,  
I need some help in my new solar system  
I Need to install new solar system but my daily watts is not that huge amou
nt, I'm using this system as a Back up system with around 300W for 6 houres
.I have one old 48 inverter working good and two 24 solar panels but so I'm
 planning to make the whole system working as 48v system.  
What is the disadvantages of installing 48v system for low wattage system?

if you have 300 watts of solar (two 24v 150w 6a panels?) , and 6 hours of f
ull sun, that's 1.8 kWh's of solar. A 48v system is fine. Just don't use mo
re than about 1.2 kWh of daily load.
