TLDR Review: POWLAND 100A MPPT Charge Controller
Pros
- •Outperforms many highericed charge controllers and delivers efficient charging, especially over several months of heavy use.
- •Handles high current and voltage effectively, managing inputs like 20A at 60V and supporting large battery banks such as 800Ah or setups with multiple solar panels.
- •Sturdy, weluilt construction with terminals spaced to prevent accidental shorting and easily accommodating thick 2 AWG wire.
- •Compatible with a broad range of voltages (12V, 24V, 36V, 48V) and works well with older solar panels and different battery types, including open acid and lithiuon batteries.
- •Clear, easo-read LCD display simplifies configuration and solar output monitoring; manual is straightforward and user-friendly.
- •Automatically recognizes system voltage and accurately operates with near 100% efficiency, showing only about a 1% difference compared to a voltmeter.
- •Reliable for multanel solar setups and works with large inverters (e.g., 3000W 24V).
- •Keeps batteries topped off for most of the day, even during less sunny conditions, maintaining battery health effectively.
- •Includes a onear warranty, offering some peace of mind for buyers.
Cons
- •Charging performance can be inconsistent, especially with 24V lithium Tesla battery setups, sometimes not reaching full boost voltage and requiring additional chargers to achieve full charge.
- •Charging may degrade over time, as noted when initial full boost charge (up to 29.2V) dropped to lower voltages (27.5V).
- •The device runs a cooling fan frequently, which users worry could affect lonerm durability or generate unwanted noise.
- •Requires manual setup to enable lithiuon battery charging mode, which, while easy, adds an extra step.
- •Needs proper waterproof sealing during installation to avoid environmental damage, particularly near walls or outdoor locations.
Bottom Line
The POWLAND 100A MPPT Solar Charge Controller stands out for its robust build, versatility across multiple voltages, and impressive efficiency that competes well against higher-priced models. However, if you're running a lithium Tesla battery system, be aware of possible inconsistent charging performance and the need for supplemental charging to reach full capacity. The frequent cooling fan operation and the necessity of manual lithium battery mode setup might be minor annoyances but can be managed. For those needing a heavy-duty, reliable solar charge controller with an accessible display and broad compatibility, this is a solid choice. If you’re primarily focused on lithium battery setups and want something with potentially smoother charging consistency out of the box, you might want to explore other MPPT controllers specialized for lithium chemistry. But for overall value and versatility across various solar and battery configurations, POWLAND’s controller has you covered.
