PowMr 15KW 48V 220V/380Vac three-phase Inverter/Charger And MPPT Solar Charger Pure Sine Wave Hybrid Inverter Charger with Parallel function POW-MKS III-5K-48V-P*3

Product Description:

The device has an integrated MPPT solar charge controller of one to two weights. It can accept the possible photovoltaic voltage, allows various photovoltaic modules to be connected, avoids the use of combiner boxes, and reduces installation costs.

Product Features:

• Compatible with Lithium batteries
• Integrated high-voltage MPPT charge controller(s). 
• Integrated AC battery charger
• Up to 9 inverters can be connected in parallel, 3-phase or split-phase for up to 58.5 kW of synchronized AC power
• Galvanic isolation of battery allows positive or negative grounding of the same
• Datalogger with up to 60 days of data storage
• Charge controller(s) function(s) even if the inverter is turned off to keep batteries fully charged
• Functions even without an expensive battery to reduce energy consumption from the grid with minimal investment
• Detachable display/communication unit with 6 LEDs and an intuitive LCD screen
• High level of connectivity: BLE, USB-OTG (on-the-go), CAN Bus, RS-485, RS-232, relay for generator start
• Integrated buzzer for error indications
• Washable filter reduces dust buildup in the All in one inverter
• Grid feed-in option is code-protected to avoid accidental feed-in


This 48V inverter can be used in parallel with two different operation modes.
1. Parallel operation in a single phase with up to 9 units. The supported maximum output power is 45KW/45KVA.
2. Maximum nine units work together to support three-phase equipment. Seven units support one phase maximum. The supported maximum output power is 45KW/45KVA and one phase can be up to 35KW/35KVA.

Package Listing:

  • Inverter---3pcs;
  • Clamp Sensor---3pcs;
  • Power Cable---3pcs
  • English Manual--3pcs;
  • Wifi(Optional)

We have an off grid house where the power intake is designed for use with a 3 phase generator and a battery solar inverter system. When the generator is running, it is powering all 3 phases and all the consumers in the house gets power. BUT, when we run on batteries and a 12V to 230V invert, single phase, only 50% of the power consumers in the house gets power. Now we want to increase our battery bank and solar panels (and upgrade to 48V DC). There is no problem in getting a 8kW inverter that creates 8 kW 220V/50Hz single phase. The problem is that we need 3 phase in order to feed all the household consumers at the same time. All I can find about single to 3 phase frequency converters is that they are only designed for motors, and I have been explained that they cannot be used in the way I explain above. Why I do not know. So… Do you have equipment that can do what I ask ? The consumers are : Lights, TV, refrigerator, water pump, electric water heater etc. Water heater and water pump is on the same phase. I believe they max out at 4kW. Then we have light, refridgerator, TV coffee maker on the other phase. So 7,5 kW inverter should be good. Hope you have time to comment this.
