Q:How to choose an inverter that suits you?
A:Please confirm your loads, battery capacity and voltage, solar panel string capacity; you can contact us for professional help

Q:Who we are?
A:We are a MUST source manufacturer, selling original MUST products

Q:What Is an Inverter Charger with MPPT?
A:It is an Integrated unit with MPPT solar charge controller, pure sine wave inverter, and battery charger in one compact unit to let you enjoy the stable power from the sun and the utility grid to keep you powered under any circumstances. PV1800 VHM 3KW Solar Inverter Charger combines solar charging, AC/generator battery charging, and battery inverting into one convenient solution to take your off-grid system to the hybrid level.

Q:Can I use this inverter to charge my batteries?
A:Yes. Compatible with 24V battery banks, this solar inverter charger keeps your battery charged with solar panels and AC/generator.

Q:Can I use the inverter with a 48V system?
A:No. This model can only work with 24V battery system.

Q:How many solar panels can I connect to this inverter?
A:For example Vmp 30.9Vdc, Imp 8.42A, Voc 37.7Vdc, Isc 8.89A 250W solar panel, you can connect 21pcs of it to our inverter, 3S7P

Q:How do I hook up the Inverter? What size cable should I use, and is it included?
A:When connecting the inverter to the battery and solar panels, please read all of the instructions and cautions in the manual before beginning the installation. The minimum recommended wiring gauge for battery wiring is 4AWG(for a 100AH battery) 2*6AWG(for a 200AH battery), PV wiring is 8AWG, AC input and out wiring is 10AWG.
Incorrect or improper connection points and corroded wires can cause great heat to melt the wire insulation, burning surrounding materials, and even cause fire, so ensure that the connection is tightened

Q:Can I use the solar inverter without batteries when using PV or Mains?
A:No, at minimum you need to have batteries connected to the unit. But our PV1800/PH1800 PRO series can run without battery. You can have a look at our store

Q:Does this solar inverter limit PV current? I'm not getting my full power?
A:When setting up the solar inverter, ensure Program 11 (PV Charging Current) and Program 13 (Maximum Charge Current) are set to their maximum to ensure no PV current clipping.

Q:Can I use the WIFI Module to monitor the inverter from my phone? Which WIFI Module should I buy?
A:Yes. The WIFI-PLUG is compatible with this inverter. Please choose your inverter with WIFI-PLUG to order
