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

New and improved line of MKS hybrid inverters, now with support for lithium batteries and BMS communication, higher input photovoltaic voltage, higher power, and also the possibility of remote monitoring.

MKS is a combination of a solar MPPT controller, a battery charger and a full sine wave inverter with backup from the public electricity grid. It is an easy, comprehensive and compact solution for creating your own single-phase photovoltaic power plant for a home, cottage or caravan. Just connect the battery and appliances. At the same time, it can function as a backup UPS source in the event of a power outage, and its output is purely island, so there can be no unwanted overflows back into the grid. Ultra-fast switching between battery and grid will not affect the operation of appliances. It is equipped with a very clear and backlit LCD display for monitoring operating information. Several options for the displayed data can be set. By default, the inverter operates in uninterruptible power supply mode, but you can set any priority for power supply from the grid / solar energy / battery, as well as the priority of the source for charging the battery.

- pure sine wave, suitable for all types of appliances
- integrated MPPT solar controller with voltage range 55 - 450 V DC
- single-phase island output without overflows (cannot be connected in parallel to the DS)
- clear and adjustable LCD display
- selectable working modes and priority of power supplies
- adjustable operating parameters as needed
- integrated short circuit / overload circuit breaker
- protection against overheating, overcharging and excessive battery discharge
- AGM and GEL batteries, or LiFePO4 can be used (only for experienced users)
- BMS communication support (Pylon, Pace protocol, no protocol)
- the battery can be automatically recharged from the network if solar energy is not available
- sound notification of incorrect status and malfunction
- cold start and energy saving mode function
- active cooling with intelligent control (noiseless at low load)
- RS485 / RS232 communication port
- remote management and monitoring option (need to purchase a communication dongle)
