LV6048 MPP Solar Inverter User Manual

1. Folasaga

The LV6048 is a 6000W/48Vdc grid-optional solar inverter designed for power systems in regions utilizing 110/120V single phase, 208V/240V split phase, or 208V 3-phase loads. This model is suitable for off-grid applications in the US, Canada, Puerto Rico, and other regions where 120V/240V split phase power is standard, eliminating the need for an external step-down transformer.

Each unit includes two dual 80A max MPPT solar chargers and supports up to three units in parallel (parallel kit built-in). The inverter offers high programmability via its LCD menu and supports both 50Hz and 60Hz operation, as well as dual AC or DC priority modes. It also features a generator starter dry contact and comes with the WatchPower monitoring program.

9. Important Notes and Disclaimers

There is no UL certification with this inverter. UL certification is typically mandatory only for Grid-Tie inverters (feed-in to grid) in the USA. However, if your State requires all inverters, whether Off-Grid or Grid-Tie, to be UL-compliant, then this product may not be suitable. Please verify local regulations before purchase, as returns for this reason may be subject to a maximum restocking fee of 20%.

This unit is not designed for use in countries utilizing 220-240V type power standards, such as Europe or Africa.
