Can we use Ather Dot Charger on Solar Inverters?
The inverter’s output capacity matters the most. Also, as here it is mentioned, it becomes very risky when the power goes:
I just got my vehicle delivered today will be setting up the dot charger over the weekend to work in tandem with my off grid solar inverter system, will post my experience of charging the ather with solar panels and inverters shortly. Standby for more updates from me.
Looking forward for your feedback. Thankyou.
Dear All, Further to provide update on my previous post, I was able to successfully charge my 450x via solar and inverter, the dot charger consumes some where in the range of 4.5 to 5 Amps current with around 800 Watts power, charge from 15% battery to 100% took around 4 Hours with around 3.8 Units of electricity. So any one planning to charge their 450x on solar and inverter you need atleast 1.5kw inverter and above exclusively for charging the vehicle. Do let me know if any more information is required from my side.
A unit of electricity is 1kWh. If it took 4 hours and 3.8 units, the average rate of charge(or power) should be 3.8kWh/4hrs = 950watts.
The usable battery capacity of the 450X should be 2.6kWh. Even considering losses, why is the consumption so high, at 3.8 units?
Hello Vinith I am just sharing across the approximate numbers here and not the exact values, the load on my inverter included some other house hold load as well not just the 450x alone, I will over the period of time do exact monitoring and share the standalone metrics. My this post was to give a shout out that charging via inverter and solar is possible with minimum inverter requirements being atleast 1.5 kw
Is it consuming 3.3 units for single charge.
It’s approx number from 15% charge level to 100%, when I really get a chance to drain out the battery completely that’s when I will get correct values.
Ideally it shouldn’t consume more than 3 units as battery pack is 2.9 KWH when you charge 0 to 100%. The usable capacity in Ather 450X is 2.61 kWh. I am using solar power to charge my bike, however my system is 2.65 KW ongrid system (without a battery bank with import-export facility with dishcom) which generates around 350 units a month which powers my home load and charging of Ather. As per my reading I haven’t consumed more than 2 to 2.5 units depending upon the charge level. Most of the time I charged from 20% to 80%. Would surely like to know your inputs.
Thanks
Thanks for sharing the inputs Chetan, as I said the units number I have shared is only approximate and not actual number + it’s only for the first time I have charged after getting delivery, will share my numbers for second and consecutive charge cycles. Also I have added a seperate energy meter to the dot charger, so this time when I charge in the 450x i will get the actual units consumed along side the battery stats. I have a 6kw off grid solar system with 3kw inverter and 400Ah battery bank as my setup.
Hi Does anybody have an idea on the electrical specs of the Charger ?
Mainly the Peak watts and the sources requirement ?
I am planning to connect the DOT charger to my Luminous solar inverter .
The idea is Ather will get charged by the inverter using solar so for my normal day use the 1 to 2 units can be easily supplied by the Regalia using 800 Watt solar panels
You can refer to this thread:
Try searching for posts on the forum, you will be able to find answers to most of your queries.
Thanks I saw the post earlier I was looking for official version of the specifications which seem to be missing on the Ather webpage or documentation . e.g. pf is not mentioned so Watt is not the real measure it is only active power reactive power plays a big part and also dictates the inrush current
Most chargers are either pf compensated or PWM for PWM charger it puts a bigger strain on inverter electronics as the fault level of inverter working in stand alone mode is very low . To put simply although normal AC is 1.5 KW a 2.5 KW inverter cannot handle the starting power . If you use an inverter air-conditioner which is soft start and Pf compensated even 1.5 KW inverter will work
same reason if you see above specs a 1500 VA inverter cannot handle 1 HP ( 750 Watt) pump motor
Connecting to Grid connected solar rooftop system during daytime will reduce power consumption from EB. And even smaller setup is enough since these inverters are not directly loaded.
Ather charger efficiency mentioned in this article as 94 % hopefully they got it from ather officially

Thank you I am planning to use offgrid using islanded mode where the inverter disconnects from grid when fully charged and uses only solar plus internal battery . till battery drops to 20 % This type of installation does not require solar permit from electricity board as it is considered beyond the meter
For those interested this article although length goes into detail - Brochure-Off-Grid-backup-and-island-systems_EN_web.pdf (victronenergy.com)
That’s really a nice system. If you haven’t finalized checkout this system as well
What if we are using hybrid solar system which will pass through the mains supply beyond its normal solar capabilities when load is high?!
