This is an MPPT solar charge controller built to squeeze more usable energy out of your solar array, especially when clouds are moving through and light levels keep shifting. It's for solar+battery system owners who want a controller that hunts down the true optimum power point instead of settling for a local one.
The SmartSolar Charge Controller is an MPPT (Maximum Power Point Tracking) solar charge controller, not an inverter and not a hybrid grid-tie system. It sits between your PV array and your battery bank, converting variable solar output into the correct charge profile for your batteries. No UL 1741 or IEEE 1547 listing is stated in the source data supplied for this listing — those standards govern grid-interactive inverters and do not apply to a standalone DC charge controller of this type. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
- AC Output Voltage: Not applicable — this is a DC-to-DC solar charge controller, not an inverter. It produces no AC output.
- DC Battery Voltage: [NEEDS VERIFICATION] — not specified in manufacturer data provided.
- PV Input Capacity (Max W): [NEEDS VERIFICATION] — not specified in manufacturer data provided.
- MPPT Voltage Window: [NEEDS VERIFICATION] — not specified in manufacturer data provided.
- Continuous / Surge Charging Output: [NEEDS VERIFICATION] — not specified in manufacturer data provided.
- Does NOT function as an inverter — no AC output of any kind (no 120V, no 120/240V split-phase).
- Does NOT provide grid sell-back or grid-tie functionality.
- Does NOT include a cooling fan — cooling is passive/convection only.
- Ultra-fast MPPT tracking rated to improve energy harvest up to 30% versus PWM controllers under variable cloud cover.
- Improves harvest up to 10% versus slower MPPT controllers, per manufacturer data, under the same shifting-light conditions.
- SmartSolar algorithm actively re-locks to the true optimum MPP during partial shading, rather than settling on a local power point.
- Peak efficiency exceeds 98%, minimizing conversion losses between panel and battery.
- Fully programmable charge algorithm plus 8 pre-programmed algorithms, selected via a rotary switch — no laptop or app required for basic profile changes.
- Fanless, passively cooled design — no moving parts to fail or draw parasitic current.

FAQ
Can this charge controller sell power back to the grid?
No. This is a solar MPPT charge controller for charging a battery bank from PV panels. It has no grid-tie or grid sell-back capability.
What battery voltage is required?
The manufacturer data provided does not specify a DC battery voltage window for this model. [NEEDS VERIFICATION] — confirm your bank voltage against the manufacturer datasheet in the Resources tab before ordering.
Can I parallel multiple units together?
Stacking or parallel capability is not stated in the manufacturer data supplied for this listing. [NEEDS VERIFICATION]
Is this UL 1741 listed for utility interconnection?
No UL 1741 listing is stated in the manufacturer data supplied for this listing. [NEEDS VERIFICATION] — this unit is a DC charge controller, not a grid-interactive inverter, so UL 1741 utility interconnection listings typically do not apply to this device class.
Warranty & Registration: Manufacturer warranty terms for this model are not stated in the data provided for this listing. [NEEDS VERIFICATION] — please refer to the "Resources (System Manuals and Warranty)" Tab above on this page for the manufacturer's warranty document, or contact us before you order and we'll track it down for you.
