Hello
Today, I'd like to introduce you to our SP Junior Series of off-grid modified sine-wave inverters.
These inverters use PV DC power to provide dual DC/AC energy.
They are ideal solutions for off-grid solar home systems or commercial applications.
These all-in-one inverters combine an inverter with a solar charge controller.
Ranging from 300 to 5000W,
they come in 12 or 24V with a 50 to 60Hz CPU controlled output frequency.
As you can see here, these inverters range from 100 to 240V.
The built-in 3-stage intelligent charger automatically charges
Ni-cad, GLE/AGM, flooded, sealed or wet batteries,
without the risk of overcharging.
And delivers an output current of up to 30A.
This optimizes solar system usage and lenghtens the lifetime of your batteries.
These inverters have a very compact form-factor design,
making it compact and light weight.
These different samples are here to show you the appearance and size of the
SP300
SP600
SP 1000
SP 1500
SP 2000, SP 2500, SP 3000
SP 4000 and SP 5000
Let's have a look at the main interface.
You can see that the SP300 and 600 have dual AC and DC outputs,
with a USB port directly on the unit.
This is very convenient because
sometimes you may want to use them as a mobile solution
and directly charge your mobile phone, for example.
The other models don't have a USB port on the inverter,
so the DC Terminal has to be used to charge DC loads.
You can see that the models over 2kW have two built-in AC sockets.
All the different inverter include a power switch,
a DIP switch to set the type of battery,
LED indicators to better control the system status,
and terminals for the solar input and DC output.
Models over 1000W also include a remote control port.
On the other side you can see the battery terminals and
the automatic cooling fan.
Models over 3000W include two fans.
For advanced applications with higher capacities,
we strongly recommend that you combine anyone of these inverters
with one of our PWM or MPPT solar external chargers.
