I found a solar inverter only $150 but Deye SUN-5K-SG04LP3-EU need $2169? Why the price has such huge difference? How to choose the right solar inverter for me?
Some factors we need to pay attention before order your solar inverter
1, 1-phase or 3-phase
3-phase inverter is more efficient than 1-phase inverter, and the output voltage could reach to 480V, so choose the one fit with your local grid requirement is necessary, you can’t use 1-phase solar inverter to work in 3-phase grid-countries, make sure check it out and then buy the inverter you need
2, On-grid or Off-grid inverter
If you wanna selling electricity to the city-grid, On-grid solar inverter is the core components for it; And in the normal standards, the warranty for Off-grid inverter around 1-2 years, but On-grid is 5years even 10years; Otherwise, on-grid inverter may have different certificate, please notice to check the certificate is fit with your countries standards, For off-grid, you must make sure the power is high than your needs, otherwise, it can’t work but on-grid can.
3, Hybrid or String
String inverter is used for saving money by selling electricity to the grid or demands, but it can’t be used for battery, so string inverter is cheap than Hybrid, you need to buy Hybrid inverter if you wanna settle battery in your solar projects
4, Reliable Quality
Renowned brands not only famous to us but testifed by enormous clients, so they worth of trust, and we can find their services center if some thing goint to wrong, some cheap products may like a baby, no one wanna be the first user, especial for electricity devices
SUN-5K-SG04LP3-EU is hybrid solar inverter with 3phase, and it could work on 40-60V battery, it is hard to find a 5kw solar inverter with 3phase as well as it could work on low-voltage battery 40-60V, so that’s the reason why the price is high but good quality
