Hybrid voltage converter CARSPA MKS4K-24 24V/3800W

Product detailed description

A new and improved range of MKS hybrid inverters, now with support for lithium batteries and BMS communication, higher PV input voltage, higher power output, and remote monitoring capability.

The MKS is a combination of a solar MPPT controller, a battery charger and a full sinusoidal inverter with backup from the public power grid. It is a simple, complete and compact solution for creating your own single-phase PV power plant for your home, cottage or caravan. Just connect the battery and appliances. At the same time, it can act as a back-up UPS power supply in the event of a grid failure, and its output is purely islanded, so there can't be any unwanted flow back to the grid. The ultra-fast switching between battery and mains will not affect the running of appliances. It is equipped with a very clear and backlit LCD display to monitor operational information. Several display options can be set. By default, the inverter operates in uninterruptible power supply mode, however, any grid/solar/battery power priority can be set, as well as the source priority for battery charging.

- pure sinusoidal waveform, suitable for all types of appliances
- integrated MPPT solar controller with voltage range 55 - 450 V DC
- single-phase island output with no flows (cannot be connected in parallel to DS)
- clear and adjustable LCD display
- selectable operating modes and priority of power supplies
- adjustable operating parameters as required
- integrated circuit breaker against short circuit / overload
- protection against overheating, overcharging and over-discharging of the battery
- aGM and GEL batteries or LiFePO4 batteries can be used (only for experienced users)
- bMS communication support (Pylon, Pace, no protocol)
- the battery can be automatically recharged from the grid if solar power is not available
- audible warning of faulty condition and fault
- cold start and power saving function
- active cooling with intelligent control (noiseless at low load)
- rS485 / RS232 communication port
