Its 100 V maximum PV input is the typical rung, so it scores 5 on operating range.
Better on operating rangeRenogy Rover Lite 60A ControllerRenogy's product page gives a 150 V maximum solar input. $249.99Scores 7.0It has Bluetooth built in, a user-definable battery type for setting LiFePO4 charge voltages, a remote temperature sensor and a 20 A load output, but no parallel or networked operation is stated, so it scores 7 on features.
No certifier directory lists this unit (Intertek, UL, CSA, LabTest, TÜV, SGS), and LiTime's page and manual name no safety listing, so it scores 2 on verification.

LiTime is the brand of Shenzhen Ampere Time Digital Energy Technology, founded in 2018 and renamed from Ampere Time in December 2022.
It sells direct from litime.com, which ships US orders from warehouses in Los Angeles and Dallas, and through its Amazon store and Walmart's marketplace.
The LiTime L24V30A-MPPT-BT-B1 is a 30 A MPPT solar charge controller for 12 V and 24 V batteries, with Bluetooth built in and read through LiTime's "LiTime Solar" app. It takes up to 100 V of open-circuit panel voltage, tracks from battery voltage plus 3 V to 76 V, and accepts up to 450 W of panels on a 12 V bank or 900 W on a 24 V bank, charging batteries from 9 V to 32 V. LiTime's product page claims 99 percent tracking efficiency and up to 98 percent peak conversion efficiency; the full manual on LiTime's manual page lists 99.9 percent tracking and gives conversion efficiency as 97 percent (printed "<97%"), with a no-load draw of 12 mA at 12 V and 10 mA at 24 V. It ships set to 12 V LiFePO4; the battery types are FLD, SEL, GEL, LI and a user-definable USE type with charge voltages set from 7 V to 15 V. A 20 A DC load output runs in manual, timer, dusk-to-dawn, test or always-on modes, and a remote temperature sensor in the box stops lithium charging below 32°F (0°C) and resumes above 41°F (5°C), a function that is off by default. The die-cast aluminium case is rated IP32, measures 9.65 x 7.09 x 3.25 in and weighs 4.41 lb, with an LCD, four buttons, LED indicators and an RS485 port (RJ12); the box holds the sensor, a magic sticker, six copper wire connectors, six heat-shrink tubes and mounting hardware. It operates from -31°F to 113°F. LiTime sells it at $132.99 and a Like New unit at $97.99 with a 1-year warranty; new units carry LiTime's 3-year charge controller warranty.
