Battery Temperature Sensing

Applying the proper charge voltage is critical for achieving optimum battery performance and longevity. The

ideal charge voltage required by batteries changes with battery temperature.

The Battery Temperature Sensor allows the charger to continuously adjust charge voltage based on actual

battery temperature. Temperature compensation of charge voltage assures that the battery receives the proper

charge voltage as battery temperature varies. The temp sensor sends precise information to the charger,

which automatically adjusts voltage to help ensure full battery charge depending on the ambient temperature

of your battery.

When the battery voltage is over 104℉ it will reduce the charging voltage by 0.1Vdc with every degree of

temperature rise. AIMS recommends using the battery sensor to protect your batteries and to provide optimal

charging. The Bat Temp Sensor attaches to the side of a battery, closest to the negative terminal using

electrical tape or silicon.

Battery voltage recovery start

After low battery voltage shut off (10V for 12V model or 20V for 24V model or 40V for 48V model), the

inverter restores operation after the battery voltage recovers to 13V/26V/52V (with power switch still in

the “On” position). This function helps users and saves time and extra labor to reactivate the inverter

when the low battery voltage returns to an acceptable range in renewable energy systems. The built in

battery charger will automatically reactivate as soon as city/generator AC has been stable for 15 seconds.

WARNING

Never leave the loads unattended, some loads (like a heater) may cause accidents in such cases.

It is better to shut everything off after low voltage trip than to leave your load on, due to the risk of fire.

Conformal Coating

AIMS Power's entire line of Global LF inverters have been processed with a conformal coating on the PCB,

making it water, rust, and dust resistant as well as corrosion resistant.

While these units are designed to withstand corrosion from the salty air, they are not splash proof.

2.5.14 Automatic Voltage Regulation

The automatic voltage regulation function is for full series of APS Pure Sine Wave Inverter/ Charger except

Instead of simply bypassing the input AC to power the loads, the APS series inverter stabilizes the input AC

voltage to a range of 230V/120V±10%.

Connected with batteries, the APS Series inverter will function as a UPS with max transfer time of 10 ms.

With the unique features our inverter provides, it will bring you long-term trouble-free operation.
