Last updated October 9, 2026. Specs for Missouri Wind and Solar come from the maker’s product pages (checked Oct 9, 2026). Specs for the other four come from their seller listings when this page was first written and were not re-checked against a maker datasheet. This is not a ranked list or a lab test.
A wind-solar hybrid charge controller lets one battery bank take power from a small wind turbine and solar panels at the same time. Below are five controllers sold for that job, plus the two questions most buyers miss: whether the controller can charge a lithium battery, and why a turbine needs a dump load.
Short answers
- Can a hybrid controller charge LiFePO4? Not always. Missouri Wind and Solar says its diversion hybrid controllers are not compatible with lithium batteries (lead-acid and AGM only). Check the battery-chemistry line for any controller before pairing it with lithium.
- Why a dump load? A spinning turbine should not just be disconnected when the battery is full. A diversion controller sends the surplus to a resistor bank (the dump load) instead.
- Can a plain solar charge controller run a turbine? Usually not. Many small turbines put out AC and need a brake and a dump load, which a solar-only controller does not provide.
Already have panels and want to add wind? See our residential wind turbine kits page first, since the turbine’s voltage and output type decide which controller fits.
Wind Solar Hybrid Charge Controllers
A wind-solar hybrid controller is a device that can combine and regulate current from two alternative power sources: solar and wind turbines. In the past, we used to have only large industrial-grade turbines, but there are a lot of small and compact wind turbines today for residential and other small-scale applications.
A hybrid controller is definitely an essential part of a hybrid power system. That being said, you need an exclusive hybrid charge controller to smartly blend the two sources for off grid power in your home or anywhere else.
The five below are listed in no particular order. They differ mainly in system voltage (12, 24, or 48 V), how much turbine and solar power they accept, whether they use MPPT or PWM, and which battery types they support.

Can a wind-solar hybrid controller charge a lithium (LiFePO4) battery?
Not always, and often not. Many diversion-style hybrid controllers are built around lead-acid charging. Missouri Wind and Solar states that both its 1200 W dump-load controller and its all-in-one 3-phase controller cannot be used with lithium batteries. For the other four controllers on this page, read the battery-type line on the current listing or manual; do not assume LiFePO4 support.
If your bank is LiFePO4, look for a controller whose maker names lithium or LiFePO4 as a supported battery type and lets you set charge and float voltages that match your battery maker’s numbers.
Why does a wind turbine need a dump (divert) load?
A solar panel can simply be disconnected when the battery is full. A wind turbine usually should not be left spinning with no load, because it can overspeed. A diversion controller keeps the turbine loaded by sending surplus power to a dump load, usually a bank of resistors that turn it into heat. Missouri Wind and Solar’s kit, for example, ships with a 1200 W, 4-resistor divert load.
Many turbines also need a brake switch for storms and maintenance. Check whether your controller includes one or whether your turbine maker sells one separately.
PWM vs MPPT on a hybrid controller
Of the five controllers here, the MarsRock listing describes booster MPPT, while the Tumo-Int and iSunergy listings describe PWM step-less unloading. MPPT tries to pull more power from panels or a turbine whose voltage doesn’t match the battery; PWM is simpler. Neither label tells you the real output on your site, which depends on your wind speeds and panel placement.
Why Solar Wind Power
Solar and wind each have a gap: solar works only in daylight, and a turbine works only when the wind blows.
Combining them can fill some of those gaps, such as windy nights or winter storms, but it does not guarantee power around the clock. Calm, cloudy days still happen, so size the battery bank for them.
For the turbine side, see residential wind turbines and solar kits. Some brands, such as Eco-Worthy, sell wind and solar bundles; you can also build your own if you match the turbine, panels, controller, and battery voltage.
Frequently Asked Questions
Can a Solar Charge Controller Work with a Wind Turbine?
Usually not. A solar-only controller is not built to handle a turbine’s AC output, overspeed, or dump load.
You need a specific controller for solar and wind sources of green energy, but a hybrid controller can manage both power sources. So if you have a hybrid controller, you can interchange it with any of the sources as per their availability. Learn more about this topic here.
What size dump load do I need?
A common rule of thumb is a dump load rated at or above the turbine’s maximum output; follow your turbine and controller manuals. Missouri Wind and Solar ships 1200 W and 600 W divert loads with different controller models.
Does a hybrid controller work at 48 V?
Some do. Missouri Wind and Solar sells 12, 24, and 48 V versions, and the Tumo-Int controller on this page was listed for 48 V. The Aleko and MarsRock listings were 12/24 V.
Will wind and solar together give me power all night?
Only when the wind blows. A turbine can charge at night, but on calm nights the battery carries the load, so size the bank for your longest calm, cloudy stretch.
Final Thoughts
Pick the controller by three things: system voltage, battery chemistry, and turbine output. If your bank is lithium, rule out any controller whose maker says lead-acid or AGM only.
Size the dump load to your turbine per its manual, and make sure the turbine has a brake.
A mismatched controller can overcharge or undercharge the battery, so check the maker’s manual before you wire anything.
