BENEFITS OF GOING SOLAR

Key benefits of commercial solar energy solutions:

  • Substantial tax benefits - the capital spend on solar can be depreciated over a year (South African legislation: Section 12B).  
  • Markedly reduce business overheads and increase your bottom line with up to 100% savings on daytime electricity costs.
  • Adds a capital asset to the property thus increases the net worth of the business.
  • Added energy security by pre-purchasing your energy today at a fixed unit cost that will protect your business against foreseeable increases in utility prices.
  • Reduce your reliance on the National Grid.
  • Improve your reputation by contributing to the savings of tonnes of yearly global carbon emissions.
  • Added insulation:  Solar PV panels provide shading thus reducing the need for cooling.

Redflow's ZBM 2 Zinc-bromide batteries supplied by Specialized Solar Systems that were installed in Mossel Bay

The benefits of Redflow ZBMs compared to other batteries

  • Delivers 100 per cent cycle depth of discharge without any risk of battery damage
  • Retains its full 10 kWh of storage capacity for its warranted 10-year life, unlike other battery types which lose significant storage capacity with age
  • Requires no reserved capacity, unlike other battery types that must reserve a portion of their storage capacity to avoid damage to their battery
  • Has a bromide-based electrolyte which is a natural fire retardant additionally mechanical damage does not risk explosion or ‘thermal runaway’
  • Operates at temperatures as hot as 50°C without active cooling
  • Offers unlimited shelf life: You can switch off a ZBM at any state of charge (SOC), hibernate it for extended periods of time, and then restore it  within 60 seconds
  • Has a great recycling story, made with major components that are easy to recycle or reuse
  • Is a modular system, it is straightforward to connect multiple ZBMs to deliver more energy storage for larger energy storage requirement. As there is no degradation over time, batteries can be added on at any stage
  • The Redflow ZBM is a great battery choice for either AC or DC power, on-grid or off-grid storage energy systems, or a bit of both.
  • 24/7 battery management allows you to use an easy web-based browser via smartphone or PC to set up, monitor, and control your ZBM
  • It also reports battery status and operational information that lets your AC inverter/charger optimise the use of the energy stored in your ZBM

Redflow energy storage

“We are seeing savings because we use the batteries to supply power during the most expensive time of the day… we are very happy with these batteries, which keep getting better over time.”Bosco Printed Circuits Director Philip Verheul

 

Bosco Printed Circuits ZBM2 benefits

South Africa’s largest manufacturer of printed circuits, Bosco Printed Circuits, has eliminated twice a week power cuts that had disrupted production, delayed deliveries and cost more than 100,000 rand a year by deploying Redflow ZBM2 zinc-bromine batteries. Bosco has also reduced its electricity costs by minimising grid use during peak demand periods in the morning and evening
– when charges increase by 300-400 percent – by running the production line on solar-generated energy and off-peak power stored in its 14 ZBM2 batteries.

PROJECT OVERVIEW

  • Location: Johannesburg, South Africa
  • ZBM2 installation partner: Specialized Solar Systems http://www.specializedsolarsystems.co.za/
  • Storage: 14 x Redflow ZBM2 zinc-bromine flow batteries (total storage capacity of 140 kWh)
  • Six Victron Quattro 48/10000 battery inverters
  • Panels: A 51kWp (kilowatt peak) rooftop solar array exclusively supplies the ZBM2 system
  • Three SMA solar inverters
  • ZBM2s provide business continuity for Bosco’s critical production line during power cuts
  • ZBM2s enable Bosco to store energy from the dedicated solar array on its factory roof
  • ZBM2s equip Bosco to charge batteries fully with low-cost electricity from midnight to 6 am
  • ZBM2s reduce Bosco electricity costs by avoiding consumption during peak demand periods
  • ZBM2s deliver 100 percent depth of discharge daily, with no storage capacity loss over time

Bosco beats power cuts with Redflow ZBM2s

South African manufacturer Bosco Printed Circuits had a big problem. The company, located in the northern industrial city of Johannesburg, often had its production line stopped by sudden power cuts.

While some power outages were scheduled in advance, others happened unannounced, which meant Bosco’s production line would stop mid-shift. As well as wasting unfinished raw materials, these stoppages disrupted Bosco’s tight delivery schedule, damaging the company’s brand.
Power cuts caused by an unreliable electrical grid could happen as often as twice a week, imposing a heavy cost on Bosco in lost production. Tolerating this situation was untenable for Bosco, South Africa’s largest manufacturer of printed circuits, which serves many customers in the Mining, Security and Industrial electronic industries.

In 2016, Redflow partner Specialized Solar Systems deployed an energy storage system using Redflow ZBM2 zinc-bromine flow batteries for Bosco. With 14 ZBM2s and six Victron Quattro 48/10000 battery inverters, the system stores grid power from off-peak periods as well as energy generated by 51 kilowatts peak (kWp) of dedicated solar panels. Bosco uses an additional 250 kWp of solar panels to power other areas of its operation.
Bosco Printed Circuits Director Mr. Philip Verheul said the company installed the Redflow batteries to avoid loss of production. “In our process, we have electroplating lines in which we plate copper in holes, so if there’s a power failure during the process. everything in the line is basically scrapped,” he said.

“Stoppages could cost as much as 10,000 rand (A$1000) each. Even more of an issue was we lost our delivery time, which created inconvenience and concern for our customers, who depend on us.”

Today, Bosco’s production line can continue working uninterrupted if mains power drops out as the ZBM2 batteries automatically supply energy to the production line. The company has also configured the system to provide energy to its front office, so power cuts do not disrupt Bosco’s commercial and head office activities.

Even as the grid power supply has become more reliable, the Redflow-based energy storage system has continued to pay for itself by allowing Bosco to avoid buying mains-supplied electricity during peak demand periods. During these morning and evening peaks, electricity charges can increase by 300 to 400 percent.

Bosco avoids these punitive costs by charging its Redflow batteries from solar panels during the day and with low-cost power available from midnight to 6 am. The company then runs its critical electroplating production lines primarily on battery power from 7-10am and from 6-8pm, saving more than 55,000 rand (A$5500) a year in electricity charges.

“We are seeing savings because we use the batteries to supply power during the most expensive time of the day,” said Mr.Verheul.
The Bosco system orchestrates this complex daily cycle of energy optimisation using the Victron CCGX and the Redflow Battery Management System (BMS), which enables Redflow to monitor and manage the battery performance from Australia.
Mr Verheul said Bosco had selected Redflow’s ZBM2 batteries because of their unique benefits. “When we looked at lead-acid and other batteries, their lifetimes were limited,” he said.

“We decided to spend a bit more money to go the Redflow route. Its ZBM2 batteries are long-lasting, with a 10-year or 36,500kWh warranty, they work well even in hot weather, and they are easily recyclable. We are very happy with these batteries, which keep getting better over time. I have to commend both Redflow and Specialized Solar Systems who have been fantastic.”
