Product Description:

1.Features of PV Grid-Tied Inverter-Sunrous-Dual MPPT-US Maintenance-Free Operation :

Maintenance-Free Operation 

Absorbent Glass Mat (AGM) technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance. During the expected float service life of batteries, no need to check the specific gravity of the electrolyte or add water.

• Good Discharging Ability

Tight assembly technology ensures an excellent high-rate discharge performance.

Long Service Life                                                     

A unique corrosion-resistant grid alloy ensures batteries have long service life.

Low Self Discharge

Using high purity raw materials ensures batteries have less self-discharge.
