Usability
6.0 out of 10At 100 A it sits on the top rung for a charge controller, so it scores 10 on capacity.
LiTime's page and manual give 98 percent maximum conversion efficiency, so it scores 8 on efficiency.
Its 150 V maximum PV input is the 7 rung, so it scores 7 on operating range.
It has Bluetooth built in, charge parameters set in the app, and a remote temperature sensor, but no load output and no stated parallel operation, so it scores 6 on features.
No certifier directory lists this unit (Intertek, UL, CSA, LabTest, TÜV, SGS), and LiTime's manual shows only FCC, CE and RoHS marks, 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 L48V100A-MPPT-BT-E is a 100 A MPPT solar charge controller for 12, 24, 36 and 48 V banks with Bluetooth built in, read and set through the "LiTime Solar" app behind a password. It takes up to 150 V of open-circuit panel voltage, tracks from battery voltage plus 3 V to 120 V, and accepts up to 1,500 W of panels at 12 V, 3,000 W at 24 V, 4,500 W at 36 V and 6,000 W at 48 V, charging batteries from 9 V to 64 V. LiTime rates it at 98 percent maximum conversion efficiency and above 99.9 percent tracking efficiency, with a no-load draw under 10 mA at 12 V and under 4 mA at 48 V. It ships set to 12 V LiFePO4; selecting the LI type locks the system voltage, while lead-acid banks can be detected automatically. 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. It has no DC load output. The IP21 case has a cast aluminium heatsink and cooling fans with a timed quiet mode, an LCD with four buttons and an RS485 communication port, operates from -4°F to 131°F, measures 7.91 x 9.92 x 3.16 in, weighs about 5.49 lb and takes up to 4 AWG wire; the box holds the sensor, a magic sticker, four screws, four plastic anchors, four copper wire connectors and heat-shrink tubes. It sells at $282.99 with LiTime's 3-year charge controller warranty.
