Browse all iPandee solar inverter models. 7 inverters available.
iPandee is the brand of Shenzhen Ipandee New Energy Technology Co., Ltd., a maker of solar charge controllers and inverters based in Shenzhen’s Longgang District. It also sells under the Wipanda name, mainly online. The company publishes little about its history or size, so this page relies on its product documentation.
The range listed here is the eSmart4 series of maximum power point tracking (MPPT) charge controllers. A charge controller is not an inverter: it sits between the panels and a battery bank and charges the battery, and a separate inverter makes AC power. The eSmart4 recognizes 12, 24, 36 and 48 V batteries automatically, can activate a sleeping lithium battery, and offers RS485 communication with PC and app monitoring.
The model code is easy to read: in ESF48H60, 48 is the highest battery voltage, H marks the higher PV voltage version (L the lower one), and 60 is the maximum charge current in amps.
Two limits decide the array. The first is PV voltage: L models accept 150 V, the H50 and H60 200 V, and the H80 and H100 250 V. With a large panel rated around 50 V open-circuit, that means two in series on an L model, three on a 200 V model and four on a 250 V model, because a cold morning pushes voltage above the datasheet value. The working voltage must also stay well above the battery voltage for charging to start.
The second is charge current. A 60 A controller on a 48 V bank uses roughly 3.1 kW of panels; anything above that is clipped. The string calculator checks your panel’s cold-weather voltage and current against the controller’s input limits.
