Hi guys would really appreciate some advice. Is the synapse 1000w and 600w models compatible with lithium batteries. Cant seem to get a answer.

I doubt it, none of the cheapies usually have enough settings to allow Voltage control of Lithium batteries and none, that I've seen have any BMS comms options... best to avoid these, unless you love wasting money on lead acid type batteries...

Spot on. The only setting of note as per the manual is the cut out voltage adjustable 10-12V. The 3kVA Synapse does have charge settings and Bluenova seems to OK it for use with their 12V drop in batteries.

Thanks for the replies appreciate it. So what about these 7ah lithium batteries for house alarms and gate motors how will they charge?

All lithiums will have the same problem being charged by the inverter. Although it seems it will charge a lithium up to 13.7V but will never be able to balance due to the low bulk voltage. 14.2V at least is required.

Hello. This might be a stupid question but am a newbie to this new world of inverters, thanks to Eskom. Someone gave me a synapse 1000w inverter and when I plugged the inverter into the wall socket and pressed the on button nothing happened. I came across some info about a Meccer inverter where if the inverter is not connected to the batteries, the unit won't switch on...is this the case with the synapse 1000w inverter or is the inverter just not working? I wasn't given the manual and cannot find it anywhere on the internet. Please help this newbie.

Yes you most connect the inverter to a battery.Check on the side of the inverter if it is 12 or 24v.

 

That inverter can't provide backup power without batteries. It will charge the batteries when there is grid power, and discharge the batteries when the grid goes down.

Hi..after I replaced both batteries to 220ah X2 on my synapse 1000w inverter my inverter doesn’t want to charge anymore 

Hi all…I have changed batteries on my synapse 1000w inverter to 2 X 220ah batteries but now my inverter doesn’t want to charge 

Hi…I have changed batteries to 2X 220 ah batteries on my synapse 1000w inverter but now it won’t charge

What kind of battery make and type did you buy.
