MakeSkyBlue Solar Inverters

MakeSkyBlue is a China-based maker of MPPT solar charge controllers and small inverters, sold mainly through its own online store and marketplaces. The range covers waterproof controllers and models for lead-acid and lithium batteries from 30 to 100 A. Official company information is limited, so the datasheet and manual are the main references.

MakeSkyBlue charge controller range

The V124 is the current MPPT line: Wi-Fi-enabled controllers rated 60, 80 and 100 A that work with 12, 24 or 48 V battery banks, lead-acid or lithium. At 48 V that corresponds to roughly 2.9, 3.8 and 4.8 kW of charging power.

What MakeSkyBlue is known for

Compact controllers for DIY off-grid builds — vans, cabins, sheds — with phone monitoring built in. Support and documentation come from the online seller rather than a local installer.

Sizing panels for a MakeSkyBlue controller

The V124 accepts at most 160 V from the panels, and its listed tracking window runs from 72 to 150 V. Three 41 V panels in series read about 123 V, or 135 V on a −10 °C morning — inside the limit; a fourth would push the string past 160 V and risk the controller. Remember that the charge current, not the panels, sets the ceiling: a 60 A unit on a 48 V bank uses about 2.9 kW of panels, and more is simply wasted at midday. The string calculator checks your panels against the controller’s voltage and current limits.
