Latest firmware to make generator charging less fussy.
Be sure to set setting #03 to APL
We don’t sell proprietary modified equipment that ties you to a specific supplier for life (“not Network Locked”) thus firmware and hardware directly from the manufacturer (MPP Solar) will be supported by our products, Note: there is a proprietary version with 500V MPPT inputs that will “Hotel California” to that supplier for life (Firmware and Hardware)
We carry the 250V Solar Input Voltage model, other models have nearly double the standby current  (currently about 0.6A per unit),  a recent youtuber showed the 390V models drawing u8p to 1.2A on Standby.
note , this firmware will only work on models bought from watts247.
The LV6548 is the latest members to our 120V/240V SPLIT PHASE inverter family and we are pleased to confirm it has UL1741 compliance (TUV certified) for US markets. Similar to the LV2424, a single LV6548 is a 120V output inverter, however split phase output (120V/240V) can be configured by using minimum 2 or more units in parallel.

This unit is unique with the following attributes:


  1. USA Warranty 2 years for our website customers
  2. Telephonic support (In English) out of Utah
  3. We are the defacto MPP Solar distributors

  5. Can offset your utility power by directly supplying loads from your solar panels  (“net zero” effect) when running with or without batteries
  6. 120A Mppt at max 250Voc – 2 x ( 4kW MPPT Charge Controllers)
  7.  Each MPPT input is completely independent from the other, max 250V input per Input (4kw max array size per input),
  8. 120A Utility Charger (120A at 48V = 5.7kW or 48A at 120V)
  9. Built in Genset dry contact start/stop relay
  10. Lithium / LiFePO4 , AGM, Flooded, Silica Salt battery compatible, and more  (custom parameters can be set according to any battery between 40 and 62V
  11. Can be timed to only charge the battery via Utility power during certain hours  (load shifting to charge on off peak rates, and using the battery during peak tariffs) Very popular for our California Customers
  12. High PV Input 250V (Voc)  Open circuit)
  13. Batteryless operation (singe unit mode only) (When using two or more, battery IS REQUIRED, due to the erratic nature of solar energy)
