The PV1800 ECO is MUST's high-frequency off-grid inverter/charger for homes and small businesses that need power through an unreliable grid. It merges three devices — a pure sine wave inverter, an MPPT solar charge controller and an AC battery charger — so a solar array, the mains and a battery bank feed one box that keeps the load running whichever source is available.

Two versions are stocked. The 3.6 kW PV18-3624 ECO runs a 24 V battery bank and takes up to 400 V of panel string voltage; the 6 kW PV18-6048 ECO runs 48 V and accepts up to 450 V. Both carry a 100 A maximum solar charge current, so a full array can be brought in without adding an external controller.

Why it suits Iraqi installations

The dual output is the practical differentiator. Essential circuits sit on the main output while air conditioning, a washing machine or other heavy loads sit on the second, and the inverter sheds that second output on its own when battery or solar can no longer carry it — so lighting and refrigeration survive a long outage that would otherwise flatten the bank.

Because the ECO can operate without a battery, it can also be installed as a daytime solar-direct system first and have storage added later, which spreads the cost of a full setup.

Key features

• Pure sine wave output, safe for motors, compressors and electronics
• Built-in MPPT solar charge controller with a wide PV input range
• Runs from solar and mains with no battery connected
• Dual outputs with automatic shedding of the secondary load
• Overload, short-circuit and deep-discharge protection
• Cold start, so the system can be brought up from batteries alone
• Charging profiles for flooded, AGM, GEL and lead batteries (3-step) and lithium (4-step)
• Communicates with lithium battery BMS over CAN, plus RS-485, USB and an optional WiFi module
• Anti-dust kit fitted as standard
