PB 300 – 1000Wh Battery storage

The PB 300 is a complete off-grid solution that contains all the constituent parts of a solar power system within its weatherproof casing. The design is so simple that the user could quickly set up a simple solar power system to provide AC for devices with power up to 300W. It also has a 24V output that can power DC equipment.

In the casing, there is a charge controller, a storage bank of lithium-ion batteries, a DC- to-AC inverter, and a logic program that manages the whole system. All that is visible on the outside is the cable that takes the DC power from the solar panels and AC power outlet.

It can run TVs, Wi-Fi routers, lights, fans, and any other utility within its operating limits. The unit can power a mixed load with power up to 300W and battery storage of about 1000Wh. In addition to that, it is equipped with temperature control and overload protection, while a PCM card protects each battery card.

The PB 300 can operate at any time of the day and be set to ‘automatic’ mode, in which it operates only at night or when power is required. It can either operate 24hrs or be set in the UPS mode, where it operates only at night or where power cuts out.

PB 300 has four terminals (left to right):

  • 2 x Solar In;
  • 1 x 24V DC Out;
  • 1 x AC Out.

Also visible on the bottom, there is an air-intake and an outlet fan-grill.

Components of the kit:

  • Cables and connectors;
  • 300W inverter 230V output;
  • Lithium battery digital charge controller;
  • Digital voltage meter;
  • User resettable overload fuse;
  • Built-in 300W MPPT charge controller;
  • Solar Isolator Switch;
  • Battery Isolator Switch.

The installation of the PB 300 is very simple:


1) Install the solar panels using the L brackets provided and connect the cables to the 
PB 300.

2) Mount the PB 300 onto a non-flammable wall.
