  • Supports Equalization Charge up to 62V


  • Built in Genset dry contact start/stop relay
  • Lithium / LiFePO4 , AGm, Flooded, Silica Salt battery compatible, and more  (custom parameters can be set according to any battery between 40 and 62V)
  • 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)
  • Battery fewer operation (singe unit mode only) (When using two or more, battery IS REQUIRED, due to the erratic nature of solar energy)
  • Built in parallel kits/ Parallelable up to 6 units
  • Built in Wifi Transmitter
  • Dual PV inputs
  • BMS Support (Pylontech, Weco, Soltaro) – Separate BMS cable required
  • Timer for output and Timer for charging
  • Built In LED RGB panel display to show operational mode

Midnite Solar Combiner Box:

The MNPV12 will accept 12 single-pole 150 VDC breakers or ten 600/1,000 positive VDC fuse holders. It includes a 15-position PV-negative busbar, 15-position ground bus bar, and two 200 A Plus busbars for breakers or fuses. Positive busbars can be combined or separated to support two grid-tie inverters or two charge controllers. Most charge controllers and grid-tie inverters can have a common negative PV bus (except Schneider XW and BlueSky).

Solar Panels:

These are used panels in good physical condition. Manufacturing labels have been removed. Panels have been tested and have a good output. These would need to be for off-grid applications.

PowerUpESS 5.1kwh LFP Battery Rackmount

Batteries come with the brackets to rack mount but the brackets used for stacking are sold separately.

POWERUPESS  is a provider of  high quality energy storage system using Lithium Iron Phosphate . Our current model is made with   Grade-A UL Listed cells with a high quality and Reliable BMS.  The integration (closed-loop-communication) of our product with other power electronics  is seamless.

A Grade UL Listed cells, same factory as competition product

Important!  Warranty only applies if connected to MPP Solar or Growatt charge controllers  (Some charge controllers such as PWM and other MPPTs  etc drastically overcharge and can damage BMSs and cells by putting the entire Solar Array open circuit voltage directly to the battery terminals)

BMS communication, BMS IS compatible with MPP Solar and  Growatt  (cables purchased separately)
